Marcel.Kulina

Passionate developer with deep interests in mobile, cloud, CI/CD, security, and AI. Building tools that push boundaries. I don't reach for a framework — I build it from scratch. Low-level systems, high complexity, the kind of problems most engineers move past. That's where I do my best work.
