About Kristian

Kristian P.Status: Offline
Node.js / NestJS Backend Developer | API Fixes & Improvements
Velika Gorica, Croatia - 7:58 am local time
I’m a backend developer specializing in Node.js and NestJS, helping teams fix bugs, finish backend features, and polish APIs close to release.

I work with TypeScript, SQL, authentication, role-based access, and existing production codebases. My focus is on safe changes, clean code, and clear communication.

If your backend is mostly done and just needs the right person to finish it properly, I can help.
