About

Hello! You can call me Leo. I'm a Full-Stack Developer based in Ho Chi Minh City, Vietnam, with a strong focus on crafting performant, SEO-friendly, and accessible digital experiences.

I'm most comfortable working with React, Next.js, and Node.js, building scalable, responsive frontends and clean, maintainable backend APIs. I also enjoy working with tools like MongoDB, Express, and Tailwind CSS — and I’m a big fan of clean design systems and component-based architecture.

Beyond the code, what drives me is delivering meaningful user experiences and solving real-world problems. I take pride in writing reusable, scalable code, collaborating with cross-functional teams, and continuously learning and experimenting with new technologies.
