What people say
I worked with Felix on a critical and challenging project. The team needed to maintain and migrate unknown legacy code in Perl. Felix managed to fix several critical issues, to migrate the most critical modules of the system and to support other team members. He demonstrated dedication, technical knowledge and could understand and foresee the business needs. As a product manager I enjoyed working with Felix — it was easy, and I could trust that he would bring the right results for the tasks he was assigned.
When Felix wanted me to test his new project, it was clear that he is an engineer with a really positive mindset about improving himself and his work. Even though the project was still in development, he took the time to make sure it was secure. This is something not many people (or companies even) do, so all the more credit to Felix for this! I can wholeheartedly recommend working with Felix.
Working with Felix on our last project was a truly positive experience. His contributions were instrumental in the project’s success, and I genuinely appreciate his hard work and collaborative spirit. He not only demonstrates high levels of professionalism but also exceptional responsibility. I have full confidence in his abilities, and without any hesitation, I would choose to work with him again in the future.
Felix embodies entrepreneurial spirit and a can-do attitude. Our discussions have always been a source of actionable insights, thanks to his direct and positive communication. He doesn’t just spot solutions; he proactively pushes them in the right direction, making him an invaluable asset to any team or project. Happy to work together anytime.

Ways to work together
End-to-end build
I design, build, ship and operate the whole thing — architecture, backend, frontend, payments and infrastructure. Ideal when you need a product taken from idea to live.
Embed with your team
Drop into your team for a focused piece — a feature, an API, a migration or a tricky backend problem — and ship it alongside your developers.
Architecture, review & rescue
Design the system, review the codebase, or rescue a stalled or legacy project and get it back to a clean, deployable state.
Frequently asked questions
Do you work remotely?
Yes. I work remotely with clients worldwide and can be on-site within Germany when a project genuinely needs it. Most engagements run fully remote with regular async updates.
What is your tech focus?
PHP and Symfony on the backend, TYPO3 for content, React and Next.js on the frontend, and DevOps (Docker, GitLab CI/CD, AWS). I cover the full stack from architecture to deployment.
Do you take projects end-to-end?
Yes. I can own a project from concept and architecture through frontend, payments and infrastructure to ongoing maintenance — or slot into an existing team for a focused piece.
How do we get started?
Tell me the outcome you need — book a short call or send a message, and I’ll come back with how I’d build it and what it takes.
