Team extension

Team extension is the simplest way to increase your development capacity. By adding external team members, you can speed up projects in progress or kick off new projects alongside your current work. Think of it as adding new talent to your roster instantly— but at a different office.

Which Python frameworks

do we have the most experience in?
  • icon-django Django
  • icon-flask Flask
  • icon-pyramid Pyramid
  • icon-twisted Twisted
  • FastAPI FastAPI

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.

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.

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.

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.

The flexible and modern Python framework, FastAPI is one of the best tools when it comes to guaranteeing development speed in the long run. 

The framework allows you to build advanced architectures. It's based on the latest Python features which provide it with efficiency and help minimize the chance of error. It’s also very intuitive: its editor support and autocompletion mean less time spent debugging.

FastAPI is also based on and fully compatible with OpenAPI and JSON Schema, the open standards for APIs.

Python Has Power

python-has-power-section

Being part of a thriving developer community is integral to what we do at STX Next. Python Has Power is an initiative we run. It’s a chance for developers to share knowledge and stay up to date with developments.

Python Has Power is a series of online workshops and face-to-face meetings in cities around Europe. These events build close links within the developer community and improve the skills of developers, inside and outside of our company. As a result, we help our people grow and inspire others. It also means we have strong relationships with Python specialists with different kinds of expertise.

Outsourcing is a big leap for your software projects

On your path to greater velocity and flexibility, we’ve got you covered every step of the way.

What if I want to keep some of the work in-house?

Smart move. By all means, keep your existing team if it works for you. Your external team will simply complement what you’re already doing while bringing in a fresh perspective and greater scalability.

They’re embedded completely in our process to the point that there’s no difference between one of our in-house developers and one of theirs.
Junior Godoi
Software Engineering Manager, Scurri

What if I need to save my budget and cut development costs?

You can scale the team down or move development entirely back in-house.

Not only are they transparent and flexible, but they’ve been immensely helpful when we needed to scale up. When the time came to scale down, it was no problem, either.
Luka Gubo
CEO, Blocktrade AG

How will I know you’re a culture fit?

We’ve been on the market since 2005 and 99% of our clients are outside of Poland, so we have lots of experience cooperating across cultures.

STX Next has very energetic and sociable teams, and we get along well. After working extensively with their teams, we honestly see them as colleagues rather than suppliers. That’s a unique thing, and it has to do with the culture of STX—it’s something they should be proud of.

CTO / Product Director, Hogarth Worldwide

How can I be sure you’ll understand my project and what it needs?

You don’t want to just ship features; your software should help your business succeed in the market. That’s why we’ll begin our cooperation with a discovery process to understand what you’re building, for whom, and why.

They are willing to learn and understand our business. Instead of just coding to our specs, STX Next engages with us as a partner, wanting to understand, improve the code, and deliver better products.

The STX Next team has proven itself to be a solid and reliable partner in software development for the Tiqets platform. Although Tiqets’ main development team is located in the Amsterdam office, having dedicated development teams in Poland gives the company the flexibility it requires in the rapidly growing market that Tiqets operates in.

Sietse van der Laan
Tech Team Manager @ Tiqets

We were able to scale up instantly, adding developers with the specific technical expertise that we needed and then rotating them out when the problem had been solved. At a much smaller firm that would have been very difficult. So far there hasn’t been any challenge that STX Next hasn’t been able to overcome.

Matthew Brooke-Hitching
CEO @ meet.mba
Featured in logo-techcrunch-1

It was always a team that showed initiative, not just receiving instructions to deliver features but also asking why and what we were building so that it quickly became much more collaborative.

Mark McLaughlin
CEO @ Coras.io
Featured in the-telegraph-logo

We were looking to move our Python & Django development out of London, to save money but also to find a good quality Agile team approach that included some product ownership. STX Next was able to provide the high quality dev team alongside project management. This fact combined with the costs savings from moving away from London made it a simple decision.

Neal Hendey
Managing Director @ TBSeen

We met STX in the beginning of the latest cryptocurrency boom and their contribution was vital to us when managing that extraordinary demand. They quickly adapt to the company and domain, show true ownership by always acting proactively towards solution and deliver high quality work even under stressful conditions. STX is now one of the most essential partners of our business.

Çağatay Yüksel
Founder and CEO @ Koinim

The project team demonstrated efficiency by streamlining processes and supplying frequent performance metrics. Resources always communicated effectively, and the deliverables were almost completely bug-free.

Leigh Simpson
CTO @ FusePump
Featured in yahoo-finance-logo

STX Next’s development efforts have been so successful that the contract is likely to be extended, and the DevOps resources are incredibly proactive and communicative. The firm features an effective onboarding process and an agreeable project management approach, creating a seamless engagement.

Kim Steglich
Director of Operations @ BuildFax
