The short version

About

35 years of software development. Three start-ups co-founded. Hundreds of projects delivered. I've written code in more languages than many developers have heard of, led teams across time zones, and learned something new every single year. Here's where it comes from.

Career timeline
1980s

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.

1990s

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.

2000s

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.

2010–2020

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

Today

Senior freelance developer and software architect, based in Landshut. Available across Germany and Europe, remote-first but not remote-only. I work with companies that need someone who has seen enough to know what matters — and enough discipline to leave out what doesn't.

If you have a technically complex problem and need someone who can both design the solution and implement it: let's talk.
