Full-stack Engineer

Backend-focused full-stack engineer specializing in Java & Spring Boot with Angular/React on the frontend. I work across scientific, enterprise, and public-sector systems — the data-heavy, distributed kind — with a strong focus on system design and practical problem solving.

Who I am & what I use

// about

I'm a backend-focused full-stack engineer based in Tartu, Estonia. I like coding.

I'm comfortable taking sole responsibility for a software system, though I have the most experience working as part of a team. I adapt quickly, value continuous learning, and care about shipping things that hold up in production.
