About me

Get to know the person behind the code

Sanin Mulić — Full-Stack Developer

Software Developer with 4+ years of commercial experience specializing in frontend development with Angular and TypeScript, supported by solid backend capabilities in .NET and C#. I build performant, accessible, and visually engaging web applications - from interactive museum installations to enterprise management systems.

Currently leading frontend development at RootId d.o.o. and building headless CMS solutions at Blueberry Consultants. My expertise spans from interactive museum installations with Three.js to enterprise education platforms with Angular.

When I'm not coding, you'll find me playing futsal at a semi-professional level, strategizing over a chess board, or exploring new web technologies.
