Summary

Full-Stack Engineer with 8+ years of experience. Regardless of the stack I'm more of a product developer, so I start from what the thing needs to do and who is going to use it. I build web products end to end, from the first product conversation through to something shipped and polished, and I usually reach for the simpler solution before the bigger one. My work has run in production for brands like L'Oréal, the NFL, and some of Europe's best-known fashion labels. When something breaks, I take ownership of it, and I see the last 10% through.

I don't hand-write much code anymore. I direct Claude Code and Cursor, and the useful part is knowing when to throw the output away, so most of my day goes on architecture and review.
