Founder story
I grew up in Ho Chi Minh City, the kind of kid who took apart radios to see what was inside and forgot to put them back together. School called it scattered. I now call it pattern-finding — the same instinct that makes me good at building software.
I'm twice-exceptional and ADHD. For most of my life, productivity tools punished me for being myself: streaks I'd break on a Tuesday, anxiety-shaped notifications, dashboards that turned my life into a leaderboard. I started building the tools I wished existed — quiet ones, that work offline, that don't shame you when you take a break.
Today I run a small indie studio of one. I ship products in public, write in two languages, and care more about the person behind the screen than about retention metrics. If that resonates with you, we'll probably get along.
How I build
Three quiet principles that show up in every product I ship.
Your data lives on your device by default. No cloud you can't audit, no vendor lock-in. Sync is a feature, not a hostage situation.
No streaks, no shame patterns, no anxiety triggers dressed as engagement. Interfaces that adapt to your energy instead of demanding more of it.
Dark, quiet, intentional. Notifications you have to opt into. Interfaces that respect attention as a finite, sacred resource.
What I focus on
- Local-first software. Apps that work offline, own your data, and never hold it hostage.
- Neurodivergent UX. Interfaces designed without shame patterns, streaks, or anxiety triggers.
- Calm AI. On-device language models that listen before they solve.
