Engagements
What I take on.
Selected work alongside the product, remote or around Stuttgart. If it does not fit one of these, ask anyway — the shape matters less than whether the problem is interesting.
Architecture review
An outside read of a system you already run — boundaries, data model, isolation, failure modes — and a written account of what will hurt first and what it would cost to fix.
Greenfield design
Technology selection, service boundaries, data and tenancy model, and the guardrails that keep the shape intact once a team starts moving fast inside it.
Hands-on delivery
Building it, not just diagramming it. Full-stack across TypeScript, .NET, Kotlin and Go, on Kubernetes, with the CI and the tests that make it maintainable by someone else.
Open source
Something wrong with one of the libraries?
Bug reports belong in the issue tracker of the repository in question, not in my inbox — that way the next person with the same problem can find the answer.
