Building
Offline-first sync for Lumen so it stops caring whether the wifi works.
Open to new opportunities
Hi, I'm Binh —
I build software that people actually use.
Engineer, tinkerer, and relentless finisher of side projects. I care about the unglamorous parts — the latency graph, the empty state, the error message nobody reads — because that's where good products are actually decided.

Lumen
A focus companion that quietly tracks where your attention actually goes, then hands you an honest picture at the end of the day. No streaks, no shaming, no dark patterns — just data you can act on.

I'm looking for teams who ship carefully and often. If that's yours, I'd love to hear what you're working on.
