Full-stack developer with years of hands-on experience in building web and mobile applications across .NET Core, React, Flutter, React Native, NodeJS, and SQL ecosystems. I focus on scalable architecture, clean code, and practical engineering that solves real problems. I build, break, refine, and repeat until it works at scale.
I work with businesses to turn ideas into shipped products, not pet projects.
