Key Benefits & Challenges When You Hire Offshore Developers

Key Benefits & Challenges When You Hire Offshore Developers

If you are looking for custom software services with budget or infrastructure constraints, offshore software development is your answer. Going for offshore hiring implies connecting with a global talent pool and getting premium software development services without exhausting your resources. 

Offshore Development Services In Simple Words, 

Mean hiring a team of remote developers from a different country that incurs less development costs in comparison to their home country. Businesses hire offshore developers to leverage the flexibility and cost-effectiveness of remote hiring while experiencing the quality and dedication of in-house developers. 

The best part of this is that you get the flexibility to either hire developers with expertise in one area or build a team of developers to get comprehensive services. This is why companies of all sizes, from startups to established firms, hire dedicated offshore developers per their requirements.

The traces of digital transformation are evident in this new business model. With easy access to required tools, techniques, and advanced technologies for facilitated collaboration, management, and communication with remote teams, businesses are more willing to experience offshore software services. 

But just like every digital advancement, offshore development services also come with benefits and challenges. So, let us explore how hiring offshore developers can help you expand your business, along with common challenges and how to overcome them for effective hiring. 

Benefits of Offshore Hiring 

There are numerous benefits of remote hiring. You do not have to update your infrastructure, worry about the lack of space, or incur any additional hiring costs. But other than that, there are many other reasons to hire an offshore developer. 

Some of the benefits you get to leverage when you hire offshore developers 

Cost-Effective Development

Developing custom software solutions can be really expensive, especially if you hire an in-house team of developers. Maintaining resources as well as investing in both digital and physical infrastructure can get challenging. 

This is why, hiring an offshore developer and building a remote team can be a better option from a business perspective. It can be especially beneficial for non-IT businesses as they won’t have to invest in IT infrastructure as it is not their primary function either. 

By hiring an offshore team, you can easily expand your team with remote developers who will offer top-quality solutions at a comparatively lower price. 

A Diverse Talent Pool

In the present scenario, you do not have to rely only on your local talent pool for hiring someone who has the required skillset and doesn’t clash with the budget. With offshore development services, you can easily achieve that. 

Offshore hiring implies you get to choose developers from across the globe and shortlist the ones that fit all your criteria. This also gives you access to designing software products that fit international standards and quality. 

Additionally, when you hire offshore developers, you get to know about different market trends across different areas, thereby helping you create tailored solutions for your international clients as well.

Quicker Development With Offshore Developers

Though this one requires very thorough planning and active participation from every team member, if done well, it can really boost your business. When you hire in-house developers, you get limited working hours when your resources can work on the said project. 

But with a team of remote developers working from different locations and time zones, you can continue the development round-the-clock, with different members taking up the project as per their working hours. 

Doing so can benefit IT companies the most as they can design custom solutions based on newly found insights about the specific market, thereby giving them a better position in the market than their competitors. 

Saves Time to Focus on Core Business Activities

Industries like hospitality, medicine, education, and other similar ones that require IT solutions merely to streamline their processes need not invest their resources in hiring and managing IT professionals and infrastructure. 

They can consult with a reliable offshore software development service provider and let the experts handle the technology-intensive part while the rest of the organization can focus on optimizing their core business operations for effective management. 

This way companies need to invest less in the services that are secondary to their services and yet maintain relevancy by staying technologically ahead of their competitors. 

Business Growth 

When you hire offshore experts, you not only get high-level expertise and premium solutions but also get a first-hand insight into the different markets, their cultures, and know about various trends. 

This will help you understand what products and services may or may not work out in different countries. You can even add or subtract certain features to design solutions in sync with the technical knowledge and adeptness of the people of a particular region. 

So you can make mindful data-based decisions and not just rely on the guesswork of what may or may not work, thus saving your resources while increasing the revenue and leading to the company’s growth. 

Challenges Involved in Offshore Hiring

Offshore hiring is now building its stronghold in the business realm because of all the benefits offered. But very rarely do we draw our attention to the challenges that often show up when you are in the middle of the hiring process or have already hired the offshore developer.

We have listed down some of the common pitfalls that you might encounter along with the best practices that can help you overcome them. This will help you streamline and facilitate remote hiring and maximize its benefits for your business. 

Here are some of the top challenges that surround offshore software development 

Challenge #1 – Communication and Language Barriers 

Language plays a major role in facilitating effective communication across the whole organization. It can become the biggest barrier in software development as it can lead to misinterpretation and miscommunication 

To foster clear communication and an effective development journey, ensure that there is one common language that both you and your team are familiar with. The most preferred language is English. This is especially required when you are hiring from countries with a different native language than yours. 

Also, you can document the necessary information as tables, flowcharts, and documents to break down complex ideas and make it easy for everyone to understand.   

Challenge #2 – Cultural Differences 

Do you know that taking an afternoon nap is acceptable in Japan and in France, employees are expected to disconnect from work after their work hours are over, while in South Korea, it is expected that employees work for longer hours. 

As much as it is fascinating to witness different work cultures, it can become one of the biggest obstacles when you hire offshore developers for your organization. Team members hired from varied geographical locations can have different work approaches and ethics which if not addressed early on, will create an awkward work environment. 

To overcome this challenge it is essential to create awareness among employees about different work cultures and promote an active discussion between them about it. This will help them understand and accept the different nuances and be more considerate of each other’s work approach. 

Challenge #3 – Multiple Time Zone 

Remote hiring means multiple locations and their different time zones will pose a major challenge as every team member will be working as per their working hours. In most cases, this time gap affects communication, decision-making, and overall project progress. 

To mitigate this challenge, it is essential that you carefully plan, communicate and divide the work among team members in a way that it minimizes the time gap between them. You can also choose the locations in a way that your and the team’s working hours overlap as it will increase the chances of having real-time communication. 

Also, using cloud-based project management tools can also facilitate clear communication by centralizing the channels and facilitating collaboration. Offshore software development is an amazing option for round-the-clock development as well, provided you competently manage the remote team. 

Challenge #4 – Data Security 

One of the major hindrances in adopting offshore hiring is the fear of data breaches. This is a serious concern as well, for data is considered the most important element for a business to succeed. Also, these documents might also contain sensitive information which if made public can lead to far worse outcomes. 

This is why it is advised to hire dedicated offshore developers from reliable sources and ensure that all the legal formalities, including, signing necessary documents are fulfilled. 

To Sum Up

Any form of hiring whether it is offshoring or in-house, comes with its own package of unexpected surprises. While you can’t predict everything, being prepared about certain common things can make the process seem a lot less like an adventure and more like an experience. 

And it goes without saying that connecting with a reputable source to hire offshore developers can take away the bulk of the burden off your shoulders. So, we as hire tech firms hope that these points will bring you clarity so that you can hire the best talent and expand your business beyond your own expectations.

Virtual Stores In Metaverse: Transforming The Future Of Shopping

Virtual Stores In Metaverse: Transforming The Future Of Shopping


The term “Metaverse” refers to the virtual world where digital characters called “avatars” can move freely and interact with one another in real time. Virtual Reality (VR) is a technology where users access to content from their computer by donning VR goggles.

More and more businesses are establishing an online presence in the Metaverse by opening virtual shops. Companies like Adidas, Burberry, Gucci, Tommy Hilfiger, Nike, Samsung, Louis Vuitton, HSBC, and JP Morgan are included in this category.

Let us dive deep into this article, written by Hire Tech Firms to know how Virtual Stores In Metaverse can transform the future of shopping. 

What Are Virtual Stores in Metaverse?

A new kind of digital store called a “virtual store” has emerged to immerse further and engross the customer. Virtual stores, in their most basic form, are immersive, full-page visual experiences on a brand’s e-commerce site and are rendered in three dimensions and a full 360 degrees. Online shoppers can peruse the selection in the same way they would a physical store—using only their computers or mobile devices. In a metaverse ecommerce store, customers can browse products and “pick up” them as they walk around.

Why Do You Need a Virtual Stores in Metaverse?

Virtual stores are about visual, artistic, contextual, and curated online shopping. In place of the traditional grid, the graphic user interface offers consumers a more engaging, discovery-based brand experience online. For any store’s products, regardless of category or collection, custom design is now a reality with the rise of e-commerce. By showcasing products in various settings, customers can better imagine how those products would function in their own lives. Computer-generated imagery (CGI) technology, similar to that used for movie special effects, is applied in real-time in virtual stores.

Many brands see young people under 30 as a valuable demographic to target through online stores. Customers from Generation Z and the Millennial generation expect the same kind of immersive, interactive, and visually stimulating content that they find in video games and social media.

Top Brands With Virtual Stores in Metaverse

1. Microsoft

In 2010, Microsoft spent $70 billion to acquire Activision Blizzard, the parent company of popular video game franchises like World of Warcraft, Call of Duty, Guitar Hero, and Candy Crush. They claimed this action marked the beginning of the Microsoft metaverse.

CEO Satya Nadella revealed more information about Microsoft and the Metaverse’s potential future. Her prediction was that metaverse technology would function in the same way as virtual reality games. Concepts once exclusive to the gaming industry are gradually permeating other spheres, such as commerce and interpersonal relationships, making gaming a lucrative market.

She explained how avatars could be used in a virtual boardroom. While virtual meetings using avatars are novel in the business world, they have been commonplace in the gaming community for quite some time.

Microsoft is still investigating ways to incorporate the Metaverse into its existing offerings. One such effort was Microsoft’s Mesh platform, which facilitated a virtual meeting space with Microsoft Teams.

2. Gucci

In the Metaverse, treasure hunts are a common type of Game, and Gucci has capitalized on this fact. The high-end fashion house has been testing the waters of the metaverse market for some time through several NFT partnerships. Gucci uses a hierarchical access system for exclusive NFT collections, such as the Superplastic collaboration.

The Sandbox is the virtual home of Gucci’s The Vault. The 10KTF Gucci Grail is the next venture for the fashion house, and it uses a treasure hunt mechanic to encourage participants to amass assets. NFT pieces designed by creative director Alessandro Michele and a mysterious Wagmi-san will be among the exclusive prizes at the end of the treasure hunt.

3. Louis Vuitton

The storied French fashion house Louis Vuitton collaborated with digital artists Beeple to release a mobile game in honor of the brand’s 200th anniversary last year. Louis the Game gives players a glimpse into the label’s history as they guide the protagonist, Vivienne, through seven environments based on real-world fashion meccas like London, Paris, and Munich.

The history of the illustrious fashion house was also revealed to players as postcards and other memorabilia popped up randomly during the Game. Players could further personalize their in-game characters with a wide selection of LV prints. Gathering monogram candles allows access to subsequent levels.

4. Snap x New Balance

The collaboration between Snap and New Balance resulted in the release of a lens that utilizes speech recognition and augmented reality to make suggestions for presents ranging from shoes to accessories. Users can experiment with several settings in the Holiday Gifting Concierge Lens. An augmented reality (AR) unboxing showing a suggestion is available in the worldview mode.

5. Samsung

The 837 flagship store of Samsung, a South Korean technology company, is now available in Decentraland. The 837X online shop will feature the company’s newest products and announcements made at CES in Las Vegas. The three main parts are the Customization Stage, the Sustainability Forest, and the Connectivity Theater. Visitors had the chance to win exclusive digital clothing during the first few days of the event. In the future, Samsung intends to open more than 837X stores on platforms besides the Decentraland store, which will only be open for a limited time.

6. Hyundai

In October, Hyundai Motor Company unveiled Mobility Adventure, a virtual world on the gaming platform Roblox that showcases Hyundai Motor’s current and future mobility offerings. Users can interact with one another and experience Hyundai’s mobility solutions in a shared virtual environment where they can also create and personalize their avatars. 

Hyundai Mobility Adventure is the first piece of virtual experience content created by a global automotive brand for the popular online Game Roblox, and it’s aimed squarely at the generation of consumers who grew up with computers and video games. Long-term support from customers is fostered by Hyundai Motor’s Mobility Adventure, which introduces visitors to the company’s current and future products and services in the mobility sector.

7. Nike

RTFKT (Artifact) Studios, a prominent NFT-focused digital fashion label, was acquired by Nike in December 2021. Now Nike can tap into a leading digital fashion house and the CloneX avatars optimized for the Metaverse. RTFKT has already released several wearables, including NFTs, designed for use in Decentraland. Plus, they offered NFTs that could be redeemed for actual goods, and some groups were given access to limited-edition sneaker drops. All of this points to the fact that Nike has acquired one of the most powerful fashion brands in the Metaverse.

8. Adidas

Adidas unveiled its 30,000-piece NFT collection, Into The Metaverse, in December 2021. The line was designed with the Bored Ape Yacht Club, the PUNKS comics team at pixel vault, and crypto investor Gmoney. Customers could buy the NFTs and the associated physical clothing, bridging the gap between the digital and the real world.

Items like tracksuits, hoodies, and Gmoney’s signature orange beanie are available in the real world. At the same time, the virtual wearables are primarily designed for use in The Sandbox, a metaverse-like platform. The venture is a part of Adidas Originals, a lifestyle brand that focuses on sportswear, and all digital assets are secured by the cryptocurrency exchange Coinbase.

9. Balenciaga

Brands continue to use Fortnite as a gateway into the Metaverse. Balenciaga, the high-end fashion house, and the gaming industry make waves together in September 2021 when they release their first NFT wearables.

The collection includes various clothes, purses, and other accessories players can purchase and use to outfit their characters. Balenciaga and Fortnite encouraged their customers to create a signature look by promoting a lookbook campaign alongside developing a unique individual style. Participants were encouraged to walk the streets and buildings modeling their Balenciaga clothing for a chance to be featured on one of the many billboards. The highlighted NFT assets are also available for purchase at conventional retailers.

10. Disney

As the undisputed leader in the entertainment industry, Disney could not pass up the chance to further expand its empire by entering the Metaverse. Even more recently, they’ve established a brand-new position whose sole purpose is to shape the company’s narrative trajectory within the Disney metaverse.

Even though they haven’t made any official metaverse plans public, they already use technology and provide striking services similar to a streamlined and interconnected metaverse environment. One example is the MagicBand, a wristband that serves as a tracking device and data repository for a visitor’s entire visit, including admission tickets, hotel keys, payment information, and a photo pass.

Disney also released virtual tours of the parks and rides to keep their customers happy while the parks were closed due to the pandemic. These aren’t the same as what you’d find in the Metaverse, but they give visitors a taste of what they can expect from the digital world in the future.

Experiencing a Storefront vs. Exploring the Metaverse as a Customer

The need to recreate the in-store experience or build something similar in the Metaverse is real. Still, Estes maintains that “the metaverse was designed to create more engaging and enhanced experiences that provide a ‘wow’ factor for users beyond what in-store experiences can deliver.”

Even though the Metaverse is growing in popularity, she noted that stores shouldn’t get too comfortable with it yet.

Regarding customer engagement, “retailers need to also focus on strengthening those experiences,” Estes explains, citing the web, mobile, in-store, and social media examples.

Mason argued that brands shouldn’t try to replicate in-store experiences online because the two are fundamentally different mediums with different capacities for establishing emotional connections with consumers.

“The most important thing to remember is that metaverse experiences are experimental and voluntary,” he emphasized. You can’t expect users to find any value in them unless they’re entertaining and interesting. Indeed, it takes no more than a wave of the hand or a click of the mouse to switch to the metaverse experience of a competing brand. How well a company’s brand will fare in a different medium is an issue that needs careful consideration.

Companies need to plan for how their brand ambassadors will interact with customers. How serious, lighthearted, or cutting-edge will they be? How will their brand be represented visually, and what tone of voice will be used?

Furthermore, Mason suggested businesses ensure the security of their metaverse strategies.

He warned that “with any new medium, there are potential downsides. Brands should be careful that their metaverse experience is properly moderated and that people can feel safe inside that virtual space.


In sum, the Metaverse has the potential to revolutionize the retail sector by letting businesses personalize customers’ shopping experiences, streamline their supply chains, and monitor and react to shoppers’ actions in real time.

The retail sector is likely to feel the increasing effects of these technologies as they mature and gain widespread acceptance. Treedis’ e-commerce and retail solutions and the vrtual stores in Metaverse provide many possibilities for online retailers and brands alike.

There is a growing expectation that the Metaverse will play a significant role in the retail industry beyond 2023, and Treedis is positioned to assist brands in exploiting this emerging opportunity. 

Python Script For Solving mp2 Equations- An Ultimate Guide

Python Script For Solving mp2 Equations- An Ultimate Guide


The MP2 (Møller-Plesset perturbation theory) method is a quantum chemistry method that provides a way to improve upon the accuracy of molecular electronic structure calculations by taking into account electron correlation. It is an iterative method that begins with a wave function calculated using a lower level of theory, such as Hartree-Fock theory, and then uses perturbation theory to include corrections to the wave function to account for electron correlation.

In order to solve MP2 equations, it is necessary to have already performed a calculation using a lower level of theory, such as Hartree-Fock theory, to obtain an initial wave function and set of molecular orbitals. These orbitals are used as a basis to expand the wave function, and the MP2 method involves evaluating integrals over these orbitals to obtain corrections to the wave function.

One of the key equations used in the MP2 method is the energy correction equation, which is used to calculate the energy correction due to electron correlation:

E_corr = 1/4 * Sum_ijab (ij|ab – ib|aj) * (2*(ij|ab) – (ij|ba)) / (e_i + e_j – e_a – e_b)

In this equation, the indices i, j, a, and b refer to the molecular orbitals, and the (ij|ab) term represents the two-electron integral over these orbitals. The energy correction is then added to the energy obtained from the lower level of theory to obtain the final energy for the system.

To implement the MP2 method in a python script, it is necessary to have a way to evaluate the two-electron integrals and to perform the necessary summations over the molecular orbitals. This can be done using a quantum chemistry library, such as PySCF or Psi4, which provide functions for evaluating these integrals and for performing the necessary summations.

Once the energy correction has been calculated, it can be added to the energy obtained from the lower level of theory to obtain the final energy for the system. This energy can then be used to obtain other properties of the system, such as the dipole moment or the atomic charges, using appropriate equations.


In summary, the MP2 method is a useful tool for improving the accuracy of molecular electronic structure calculations by taking into account electron correlation. It involves evaluating integrals over molecular orbitals and performing summations to obtain corrections to the wave function. These calculations can be implemented in a python script using a quantum chemistry library.
