Drawing on more than a quarter-century of experience, we have honed our development process to ensure its efficiency for clients worldwide as we partner with businesses in the USA, Europe, and all over the world. 

  • 01/ Auditing

    NIX Solution Architects and Business Analysts start by looking at the client’s business needs and pain points and offering a solution to cover them best.

    Suppose you already have partially-developed product components or designs. In this case, you can share them with our experts, and they’ll suggest an efficient roadmap for delivering a market-ready web platform or application.

  • 02/ Planning

    In the second development phase, the solution architect turns the agreed product vision into a system architecture and chooses the optimal implementation approach. The choice is based on the identified project requirements and considers prospects for further web product growth and scaling to ensure it’s ready for the predicted system load.

    Our experts strive to minimize possible tech risks that might poorly affect your business. Therefore, we carefully determine the scope of work, set up the project management infrastructure, and create a development roadmap, deconstructing projects into steps.

  • 03/ Web App & Platform Development

    At the next stage, NIX developers start coding while UI/UX designers create a user-friendly web design. Project managers at this time set up communication processes to ensure smooth and effective product delivery. They also continually monitor project progress and adjust the roadmap to meet deadlines and budgets. As a client, you are always aware of what is happening, as the PM keeps you informed throughout the development journey.

  • 04/ Testing

    During testing, QA engineers go through numerous steps to ensure the created web product runs like clockwork and meets all requirements. Their task is to check whether the web platform or application demonstrates high performance, has reliable data protection, and provides flawless user experience in various use cases.

    Our experts use advanced testing practices and approaches, like TDD and BDD, to ensure the proper result.

  • 05/ Launch, Support, and Enhancements

    After a successful web solution release, our engineering team provides tech support & assistance to keep everything running at high capacity. If needed, we can further scale the project to ensure you lead the market and perform your business cost-effectively, with minimal overhead.

FAQ on Custom Web Platform & Application Development


Are custom web application development services costly?

The final price of software development depends on a number of different factors, such as:

  • Project complexity. The pricing has a lot to do with the complexity of the platform functionality, design, and the final solution’s customization level. That’s why custom web platform and application development services are more costly. 
  • Deadline. The need to work on tight deadlines will additionally complicate developers‘ work, ultimately increasing the project’s price.
  • Location. In the USA, for example, developers’ work is more expensive—the cost of web platform & application development services usually starts at several thousand US dollars. In other countries, the rate may be different and change over time.

To get a more correct estimation, feel free to contact us. As an experienced web platform & app development company, we can always find an option to suit your requirements, including financial ones.


What types of web apps and platforms can you develop?

Our web platform and app development company has successful experience working with clients in the USA and Europe, providing them with customized software solutions of various types across industries, including:

  • Enterprise web platforms, aimed at optimizing the company’s processes and customized for your specific business tasks
  • Ecommerce web platforms & apps. This software helps retailers digitize sales and solves the problems of the ecommerce industry
  • B2B, B2C, and B2E web portals focused on various business tasks and serving as access points for users, helping them explore content and interact with brands
  • Cloud-based web platforms & apps, which means moving your infrastructure to the cloud for greater system flexibility and scalability

This is just a short list of what our web platform & application development services may include. Contact us, describe your needs, and our team will suggest the best solution to solve it.


How long does it take to build a web application or platform?

The duration of web app and/or platform development depends on factors such as:

Your requirements for the product: the more features you need to implement, the longer the development takes

  • Budget. Your investment in development can also affect the project’s duration
  • Customization. A web platform or application based on ready-made solutions is faster to implement; however, it loses to custom development in terms of complexity and the ability to meet very specific requirements

We have experience delivering web platforms and applications in the shortest possible time— as short as three months. In addition, a good option for a quick launch is to start with an MVP and then gradually improve the product so that it’s fully customized to the identified user needs.


Do you provide maintenance and support after developing a web app or platform?

Of course, our web development services may include support for the created product, whether it’s a web app or a full-fledged multifunctional web platform.

In addition, we offer standalone maintenance services to ensure that your software runs smoothly around the clock.


Do you provide your custom web platform and application development services in other time zones?

Some changes in working hours are certainly possible with the consent of each expert involved in the project—but in general, we have offices in the USA and Europe, so there’s no need.

We’re focused on delivering the best product and achieving the desired result despite the time and distance differences. With our vast and successful experience working even with companies located on the West Coast in the USA, we can set up processes correctly and ensure they run smoothly and transparently.


How can I find a reliable web app development company with proven experience?

First of all, you must have a clear vision for your future web platform or application, and only after that should you look for developers in the USA or outside of it. To find the right web platform & app development company, you need to:

  • Pay attention to reviews of  the company you’re considering (it’s ideal if someone you know has already had experience with this team and recommends it to you)
  • Analyze case studies of projects similar to yours or from your industry (relevant experience and overall experience)
  • Check if the company has awards and certifications


In addition, you should understand whether it’s comfortable for you to communicate with the team you have chosen.
