About

I’m a Frontend Developer with over 5 years of experience building accessible, responsive, and secure web interfaces. My focus lies in crafting clean, maintainable code while collaborating across teams to create intuitive digital experiences.

My main stack includes React, Next.js, TypeScript, and Tailwind CSS, with experience in both frontend-heavy and fullstack roles. I’ve worked on e-wallet platforms, data dashboards, component libraries, and internal tools — always with a mobile-first mindset and strong attention to performance and usability.

I’m self-taught, proactive, and always exploring ways to improve developer experience, product quality, and accessibility. Whether it’s coding, debugging, or refactoring, I enjoy being hands-on and working closely with designers, backend engineers, and QA to bring reliable products to life.

Outside of work, I practice Shotokan Karate (2nd Dan black belt), dive into tech learning, and enjoy games with sandbox exploration and fantasy. I believe good code and martial arts share something in common: clarity, discipline, and constant refinement.
