About Me

BUILDINGSCALABLESYSTEMS

CTO & Backend Engineer with solid experience designing and leading distributed, scalable systems. Specialized in clean architectures (Hexagonal, DDD, CQRS, Microservices). Also building frontends with Next.js and React Native — not because I love it, but because someone has to. Constantly learning, keeping up with AI and modern frameworks. I enjoy the process and love finding solutions — the rest is just tools.
