About
The person behind Sidecut Labs
I'm Paul Cielo. Sidecut Labs is where I design, build and ship my own apps, from the first sketch to the App Store, and write about how they were made.
What I build
First Chair helps skiers decide where to go: snow, drive time and chain controls for up to five resorts on one screen. It is live on the App Store, with a small backend that gathers road data from 15 states.
Pocket Shapes lets you make things for a 3D printer on your phone. It is in testing, and you can try the prototype in your browser.
What I work with
- iPhone apps with Expo and React Native, in TypeScript
- Native Swift modules, such as CarPlay
- Backends on Cloudflare Workers, KV and scheduled jobs
- 3D on the web with three.js and WebAssembly
- Product and interface design, from sketches to finished screens
- The App Store release cycle: TestFlight, privacy labels, review
