Kaspar Kliimask

Full-stack Engineer

Backend-focused full-stack engineer with 7+ years across research, public-sector, and product teams. I like solving hard problems with clean, dependable systems — mainly Java and Spring Boot, with React or Angular on the frontend. Outside of work I'm into sports, electronics, and home automation.
