I've been writing code professionally since 2008, across 19 engagements at companies ranging from BMW and Lufthansa to early-stage startups. I started as a fullstack developer and have spent the last decade progressively taking on architectural and leadership scope — not because it was a career plan, but because the problems that interested me kept expanding beyond the code.
Today I work as an independent consultant, embedded in engineering teams at DACH enterprises. My focus is the intersection of technical architecture, team dynamics, and delivery — the three things that, in my experience, determine whether a project succeeds or stalls. I run my own Kubernetes cluster, build with AI daily, and have a particular interest in the old-school software principles that turn out to make you a more effective engineer in the AI era, not a less relevant one.

01
Clean and Agile
Clean code and agile practices are often taught as rules. In my experience they only become useful once you understand them well enough to adapt them to the situation in front of you. I've spent two decades refining what this actually looks like in practice — not in ideal conditions, but in real codebases with real deadlines and real team dynamics.
02
Learner and Mentor
Every engagement teaches me something I didn't know before — a different domain, a different architectural constraint, a team with a completely different failure mode. I actively share what I pick up, because the fastest way to make a team independent is to make knowledge transfer a daily habit, not a handover document at the end.
03
Automation
The most expensive work in any team is the work that happens on autopilot: manual deployments, repetitive review cycles, unclear onboarding steps repeated for every new hire. I look for these patterns early and eliminate them — not to replace human judgment, but to free it up for problems that actually require it.
