Where I'm putting energy right now
Millions of listings, billions of queries. The #1 second hand marketplace in Germany challenges our teams to deliver value at scale.
Consulting with an early-stage AI startup — helping shape product strategy, sharpen positioning, and connect the dots between what the technology can do and what customers actually need.
Building a white-label SaaS platform for smart NFC business cards — each operator gets their own branded hub and dashboard. Glastrix, an NFC print shop, is the first customer live on the platform.
Running a Berlin STR on Smoobu, I kept hitting the same gaps — cleaning handover, tax exports, Nuki setup. So I built the missing tools and put them here free: Google Sheets sync, Übernachtungssteuer calculator, and more.
Where I come from
Ten years across marketplaces, B2B SaaS platforms, and AI systems. Hover any node to explore.
What ties it together: stepping back, finding the actual problem, build a system open to learning, measure & iterate.
