About Me

Turning complex backend problems into reliable systems

I'm a full stack developer who specializes in the infrastructure businesses actually live or die by — payments and game top-up systems. I build APIs that process real money, in real time, without surprises.

Over the years I've worked with gaming stores, fintech startups, and digital goods platforms to ship production-grade systems — from real-time top-up APIs to multi-gateway checkout flows and the bots that keep customers served around the clock.

My focus is always the same: fast to ship, secure by default, and built to scale past the first thousand users.
