I'm Djordje — a full-stack engineer based in Serbia. For the past several years I've built and maintained production platforms for an international insurance group, alongside part-time work for product teams. I work across the stack — React, React Native, Next.js and TypeScript — and I care about speed, clean architecture and interfaces that feel inevitable.
