About
35 years of software development. Three start-ups co-founded. Hundreds of projects delivered. Working across dozens of programming languages over the decades built an intuition for solving problems that only comes from sustained, hands-on practice. Today that intuition is what makes AI-augmented development safe to rely on — and what AI agents get built on top of. I've led teams across time zones and learned something new every single year. Here's where it comes from.
The beginning
It started with a Commodore VC 20 — not the games console I wanted, but considerably more interesting in hindsight. BASIC led to Assembler, Assembler led to a deep understanding of how computers actually work at the instruction level. By the time the C64 arrived, programming wasn't a hobby anymore. It was a compulsion.
The craft develops
The Amiga era brought graphics, sound, and an obsession with reverse engineering. The first PC opened up networks, security research, and a brief but formative stint in the world of key generators — strictly for personal education, never distributed. HTML, PHP, and JavaScript arrived in the late nineties and never really left.
Going professional
Apprenticeship completed, Abitur caught up, computer science degree started at Georg Simon Ohm University in Nuremberg. Four years in, the client requests became too interesting to ignore. The degree went on hold; the work didn't. Linux became the foundation of everything. C and C++ joined the stack. The first proper business was up and running.
2010 onwards
Co-founded Buzzienda (word-of-mouth marketing platform, Nuremberg, 2010), 4freelance e.G. (freelancer cooperative, Munich, 2013 — Chairman of the Supervisory Board), and AMZSTARS (Amazon retail launch platform, Munich, 2016 — sold successfully in 2020). Led international developer teams. Expanded into Python, AI tooling, and LLM development. The field keeps moving; so do I.
Today
Senior freelance developer and software architect, based in Herrsching. Available across Germany and Europe, remote-first but not remote-only. Day-to-day work is AI-augmented — every generated line reviewed by a senior engineer — and increasingly means building AI agents that plug into existing systems. I work with companies that need someone who has seen enough to know what matters, and enough discipline to leave out what doesn't.
Outside of work, I'm a member of Mensa in Deutschland e.V. (MinD).
If you have a technically complex problem and need someone who can both design the solution and implement it: let's talk.
