Vend Marketplaces (formerly FINN.no)
Backend and platform work on Vend's messaging platform - four Nordic marketplaces (finn.no, blocket.se, tori.fi, dba.dk) on one codebase, ~30 microservices on Kubernetes. The part I keep coming back to: changes that start in one brand and break in four, where no single team owns the fix. On FINN.no we redesigned the messaging frontend around the seller, with conversations grouped by ad, so a seller with several ads sees who is asking about what in one place. I built the backend changes behind it, worked through the design decisions with the team, and built parts of the frontend in React, TanStack and Tailwind.
Lately, prototyping LLM features inside the messaging thread.
