About
I’m a results-driven Senior Full-Stack Engineer with 8+ years building scalable, secure, and user-focused web apps. I work across the stack with Laravel, React/TypeScript, RxJS, and AWS, designing modular systems, real-time data flows, and clean, maintainable code. I enjoy shaping service layers, performance tuning, and turning complex requirements into simple, reliable UX.
