Hi, I'm Trịnh Trung Hiếu.
Golang Backend Engineer.
I like building things that work at scale.
About
Currently focused on Golang backend engineering, with interests in distributed systems, backend architecture, databases, and cloud infrastructure.
I enjoy turning complex problems into simple, maintainable systems and continuously learning how large-scale software is designed and operated.
My goal is to become a stronger engineer by building real systems, understanding their trade-offs, and improving them over time.
