05About

How I work.

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.

Ownership

I take features from an ambiguous problem to shipped, tested and maintained — not just the happy path.

Quality by default

Typed end-to-end and covered by automated tests, so the codebase stays reliable and fast to change as it grows.

Clear communication

I work well async in a distributed team — short written updates, thorough code review, no surprises.
