(01) — About

A senior pair of hands who's shipped real products — and knows what it takes to keep them running.

I'm Michael, a full-stack developer with a decade of experience building web applications end to end. I care about clean architecture, sensible trade-offs, and code that the next engineer can actually read.

I work best as an embedded partner — close enough to the product to make sharp decisions, senior enough to own the hard parts. Whether you're validating a new idea or hardening a product that's already live, I'll help you ship with confidence.

// Roots

Rooted in Germany, building worldwide.

Home base is Burglengenfeld in Bavaria — but the work travels. I partner with founders and teams across time zones, comfortable spanning EU and US hours and shipping wherever the product needs to run.
