is a product engineer,
an open-source builder,
and a writer.

I work at charles in Berlin, building AI-native conversational commerce for consumer brands.

Product engineering, for me, means owning the whole slice — from database schema to pixels, from idea to production, and the metrics after launch.

I've done that for eight years across frontend, backend, and infrastructure at SuitePad, HousingAnywhere, Andela, Rhino, and Leafly.

I care about type systems, fast interfaces, and software that doesn't fall over.
