Developers

Over 200 developers

Ready to empower any project with well-reviewed code and a results-driven Agile process

We are Europe’s Python Powerhouse. From a single developer who decided to ditch Java and get results faster with Python in 2005, we have grown to a Python development company of over 300 professionals.

Today, our roster includes not just frontend and backend developers but also automated QA specialists, UX/UI designers, Agile experts, DevOps engineers, and machine learning specialists—roles we’ve added over the years to provide true end-to-end solutions for any business that wants to win in the tech game. Along the way, we’ve built a community of people passionate about building software that works flawlessly, delights users, and delivers business results.

Values

Transparency

Trust is built upon openness and fairness. For our team members, this means a clear salary formula and codified development paths. For our clients, it means maintaining full transparency by sharing detailed monthly time reports.

Win-Win

In any situation where we need to establish clear rules and expectations, we expect a win-win deal or no deal at all. We follow this value when negotiating contracts, starting new partnerships, or considering changes at the company.

Team Power

The best collaboration happens when one
team can work in one dedicated room on one project, fully focused. For this reason,
we don’t have open space offices
and we limit remote work.

Continuous
Improvement

We foster a feedback culture both within the organization and when working with our partners. Using Agile and Scrum, we implement feedback early and often. We also keep adding new offices, new roles, new services, new technologies, and new partnerships to the STX Next roster.

Software
Craftsmanship

The code we deliver should be not only functional, but well-crafted. To ensure this,
we set high recruitment standards, we keep refining the ways we work, and we serve as teachers for the community.

Our Team

The success of our clients and co-workers depends on smooth processes and informed decision making. We have a roster of seasoned leaders applying the best management and communication practices on the market to our work.

Their combined experience across the entire spectrum of delivering successful software projects and assembling high-performing teams has helped us become Europe’s largest Python software house.
