About
I'm a software engineer based in Ho Chi Minh City, Vietnam, with over 12 years of building consumer mobile products. Native iOS since 2013, Flutter after that, from early versions all the way to production.
My path went from writing Objective-C at an outsourcing house, to founding my own startup (ShipDauRoi, which reached the Top 50 Business apps on the Vietnam App Store), to building a global platform for Pizza Hut, to health tech at Jio Health, and now building a realtime super app at Supernova.
How I work
I like owning a feature the whole way, from architecture and technical planning through to production. The part of the job I enjoy most is what happens after launch, when the code meets real devices, real networks, and the bugs that only exist there.
Above all I believe in sharing practical knowledge. Not theory, but the real lessons that come from shipping products and serving real users.
