Experience

All the work I've done, both freelance and full-time.

I started my professional career as full-stack developer at Vietnam. Most of my work is focused on mobile and back-end development.

For me architecture and design are the most important things in software development. I always try to make my code clean and easy to understand, and I always try to update myself, follow the best practices, and learn new technologies.
