About Me

From Medicine to
Microservices

I'm a Backend Engineer with a unique background — I studied General Medicine at Pham Ngoc Thach University before pivoting fully into software engineering. This journey taught me analytical thinking, systematic problem-solving, and the ability to work under pressure.

Today, I build distributed systems and microservices for companies across Hong Kong, Japan, and the US. I'm fluent in English and love collaborating with international teams to ship products that make a real difference.
