As a Software Engineer, I build fast, scalable web and mobile applications using React, Next.js, TypeScript, Node.js, and React Native (Expo).

I adapt quickly to new challenges, communicate effectively, and take responsibility for delivering reliable solutions on time. Always learning. Always improving.

✨Your web app can run smoother, look cleaner, and do more for your users — that’s what I focus on.
