Why Leibreich Technologies

16+ years of mobile

Most of my career has been building and shipping mobile apps, including retail point-of-sale software that runs in stores across the US and internationally.

Both platforms, one codebase

React Native lets one codebase serve iPhone and Android, which keeps the apps consistent and the budget focused on features instead of duplicate work.

The whole stack, one person

The app, the API, the database and the store listing are built by the same person, so nothing falls between vendors.
Questions

Do you build native or cross-platform apps?

Mostly cross-platform with React Native, which compiles to real native apps. When a feature needs Swift or Kotlin, that code is written natively and plugged in.

Can you work from my designs?

Yes. Bring Figma files or sketches, or start from scratch and we’ll design the screens together.
