Our teams will work exclusively for you. In the majority of cases, one team sits in one room working on one project, ensuring full focus.

True project ownership

We will build your Python project as if it was our own; our reputation depends on it. We are interested in why you want to build your product, not just what it is or how to build it.

What do we promise if you partner up with us?

A true partnership only works if both sides bring everything they’ve got to the table.


Here’s what you can expect when you join forces with STX Next:


  • outstanding, non-corporate atmosphere, team spirit, and great people to work with;
  • truly Agile working environment composed of small, independent teams working in Scrum with a flat organizational structure;
  • expert knowledge and understanding of Python 2 and 3;
  • demonstrated experience with multiple Python web frameworks, like Django, Flask, Pyramid, Twisted, or others; expertise in using code versioning tools, such as Git;
  • tried and tested use of best Python practices;
  • effortless English communication skills;
  • deep awareness of the threading limitations of Python and multi-process architecture;
  • strong skills in unit testing and debugging.



Which Python frameworks
do we have the most experience in?

Django development services

Arguably the most popular Python web framework out there, Django offers a comprehensive package of all the tools you need to build your application. By providing integrated and ready-to-use solutions, the framework favors a “batteries-included” approach to software development.

Thanks to its robust and reliable tech stack, Django delivers complex solutions fast, makes your project highly scalable, and last but not least gives you stability and security. It’s also a perfect fit if you’re looking to develop an MVP quickly.

Flask development services

A microframework with all the basic functionalities of a web app, Flask is the glue that brings together Python’s plethora of extensions and libraries. Flexible, customizable, and high-performing, the framework bets on experimentation with your tech stack and doesn’t shy away from the newest technologies on the market.

When you need a number of highly specialized (micro)services or small, disparate features, you can’t go wrong with Flask. Ease of use and small code base size are also welcome additions.

Pyramid development services

Even though freedom and openness are at the heart of Pyramid, the framework is very stable and mature, offering a solid foundation for complex or highly non-standard projects. Effortless to customize with unlimited possibilities, Pyramid allows developers to use any and all practices they choose to create your software.

“Start small, finish big, stay finished”—that’s the mission statement of Pyramid. Aimed at seasoned professionals unafraid to play the long game, the framework provides an ideal setup for building features in completely new and exciting ways.

Twisted development services

One of the most mature Python projects around with a long market presence, Twisted can be used for writing asynchronous code as simple to read as regular, synchronous code. The basic functionalities of the framework can be expanded with additional extensions that allow for both application-level work and low-level programming.

Actively maintained and supported, Twisted is a great choice for writing specialized services. The advanced age and maturity of the framework also give it a unique edge over many other asyncio-based solutions.
