Hey, I'm Maxim 👋

📍 Belgrade, Serbia · 💼 Lead iOS & AI Engineer @B2Broker · 12+ yrs in the Apple ecosystem

I build latency-sensitive iOS products across automotive, fintech and trading, lead engineering teams, ship my own privacy-first macOS apps, and create AI-powered developer tools that make everyday workflows faster.
