Mobile Leader β’ Edge AI & POS Systems β’ Developer Tools
I design and ship things people actually use β mobile apps, Edge-AI & POS systems, and developer tools. From hardware integration to robust software at scale.
- Mobile apps at scale β Native Android & iOS that stay fast, reliable, and easy to grow as products reach millions of users.
- Transit & payment systems β onboard fare collection and card payments for public transport, certified with Visa, Mastercard & Napas.
- Edge AI on device β real-time human & vehicle detection that runs directly on Qualcomm silicon, no cloud round-trip.
- Developer tools & open source β tools I build in the open on GitHub, plus from-the-source field handbooks on how systems really work.
Mobile Leader @ VinSmart Future β building GoAFC + GoPS (open-loop transit payments for HCMC's Management Center of Public Transport) and XanhBus running inside the GreenSM super app.
| Project | What it is |
