About

I'm Thanh, a software engineer based in Vietnam.

I work mostly on backend infrastructure, distributed systems, and digital asset systems.

I'm currently a founding engineer at Fystack, where I build open-source custody and wallet infrastructure. Before that, I worked on backend systems and production infrastructure at Angi / mHelpDesk.

I like understanding how systems work from the bottom up — reading specifications, building things, debugging them, and occasionally writing about what I learn. I'm also interested in cryptography and computer science research.
