Engineer building intentional, durable systems that solve real problems.

I'm Ann — a full-stack engineer based in Vietnam. I work alongside businesses and founders who are frustrated that their software slows them down instead of scaling with them. My job is to figure out why, then build something that actually fixes it.

I care less about specific tools and more about choosing the right ones. Too many systems get rebuilt two years later — not because the code was bad, but because the architecture was never a decision. It was just a default. I treat every major architectural choice as a deliberate one.

When I'm not deep in a codebase, I'm studying system design, learning how industries actually operate, and looking for problems that genuinely deserve durable solutions — especially in environmental tech and mission-driven work.
