About me
I’m James Han, a full-stack developer in Orange County, California. I build software end to end: the screens people tap, the server and database behind them, and the launch, whether that is the App Store, a website or a printed QR code. Then I keep it running.
Fyt is my own product: an iPhone and Apple Watch app on the App Store since July 2026. The menus I built on my own initiative for the restaurant group where I work, in 13 languages.
How I work
- A fixed price in writing before I start.
- Plain English, no jargon.
- Every number on this site comes from a source I can show you.
What I use, and where you can see it
- Swift, SwiftUI, watchOS, HealthKit: Fyt’s iPhone and Apple Watch app.
- TypeScript, Node.js, Fastify, PostgreSQL: Fyt’s server, database and background jobs.
- Python: the menu build that makes every web page and PDF.
- HTML, CSS, JavaScript: the menus, and this site.
- Fly.io, GitHub Actions, GitHub Pages: hosting and deploys.
