Architecture as the art of trade-offs, decided with the system in mind.

4 articlesEN · DE

Architecture is not diagrams — it is the small set of decisions that are expensive to reverse, made well. Service boundaries, where state lives, how components fail and recover: get these right and a system stays cheap to change for years. Across 12+ years building platforms at scale, I have learned good architecture is mostly owning trade-offs honestly, not chasing the newest pattern.

FAQ

What is your architecture background?
12+ years designing and operating platforms at scale in large enterprise environments, as a Google Cloud Ambassador, 5× Google Cloud Professional certified. I get the hard, hard-to-reverse decisions right so the system stays cheap to change for years.
Are you available to hire?
Yes — system design, service boundaries, event-driven architecture and scalability reviews, as a contract, consulting or selected full-time engagement, remote across the EU or on-site in Germany. I work fluently in English.
How do we start working together?
Tell me about the system you are designing or struggling to change on the contact page, and I will reply with how I can help.

Designing a system you have to live with?

From service boundaries to event-driven design and resilience, I help teams make the expensive-to-reverse decisions well — and keep the architecture cheap to change.
