About
Full stack engineer with 4 years of experience building scalable web systems and APIs. I work mainly with React/Next.js on the frontend and Node.js/Go on the backend, with a strong focus on architecture, performance, and cloud deployment.
In recent roles I’ve taken on broader technical responsibility—designing system components, leading AWS infrastructure migrations, and improving reliability and scalability through load testing and performance optimizations.
