I build AI systems at Cisco / Splunk and angel invest through P1K Ventures. Based in Duisburg, often in Berlin and San Francisco.
About
I co-founded Replex, a venture-backed Kubernetes governance and cost-management company operating out of San Francisco and Germany. Cisco acquired it in 2021. Today I'm a Director of Engineering at Cisco / Splunk, working on AI.
Most of my time goes into what AI actually changes about building software: agents that write and ship real code, the infrastructure underneath them, and what both do to how engineering teams work. I run my own servers and test all of it on myself before I have opinions about it.
Through P1K Ventures I angel invest at the 0 to 0.5 stage — before the product, often before the company. In practice that means being a sparring partner on architecture, first hires, and first enterprise deals, not just a check.
Home is Duisburg. For work, you'll just as often find me in Berlin or San Francisco.
If you're building something early and think I can help — or you just think we should talk — email me.
