I'm a seasoned full-stack developer with deep expertise in TypeScript, React, React Native, Node.js, and decentralized applications. With strong hands-on experience and a background in technical leadership, I’ve led teams and delivered complex systems — but my true passion lies in building real products that solve real user needs. I focus on delivering practical, high-impact solutions rather than assumptions, and I thrive in environments where code, performance, and user experience drive everything.
