Case Study: Zedmed achieves one React Native mobile app in three days with First Line Software

Leading Healthcare System delivers one working app in 3 days with First Line Software

Zedmed Pty Ltd, an Australian medical practice-management software company, faced the challenge of maintaining two separate and costly legacy mobile apps for iOS and Android. First Line Software was engaged to unify these into a single React Native application, starting with only the source code and no documentation, API specs, or backend access.

Using its AI-native RACE Programming methodology and Claude Code, First Line Software reverse-engineered the code into specifications and built a documented, tested application in just three days. The solution replaced two codebases with one, slashing maintenance overhead and delivering a demo-ready app with full test coverage and visual parity with the originals.
