Background

About Me

I am a Computer Science graduate based in Ho Chi Minh City, Vietnam. My journey into software engineering started with a fascination for how large-scale services process millions of operations seamlessly without breaking data integrity.

Over the past few years, I have invested deeply into building resilient APIs and backend services using Java (Spring Boot) and TypeScript (NestJS). I prioritize maintainable architecture, structured domain layers, and defensive database design (indexing, caching with Redis, ACID transactions).

Beyond enterprise web frameworks, I enjoy exploring lower-level systems programming in Rust to gain a stronger intuition for memory safety, concurrency, and zero-cost abstractions.
