About Me

I'm a UI Developer with 9+ years of experience building responsive, scalable, and accessible web applications. I specialize in Angular, React, and TypeScript on the frontend, and I'm comfortable extending into Node.js, Spring Boot microservices, and AWS on the backend. I'm passionate about translating great designs into great products — with a strong eye for performance, accessibility, and clean architecture.
