Context
Mistral AI was evolving Le Chat mobile during its hypergrowth phase. It needed a senior React Native engineer able to own native workstreams end to end, inside the team’s repo and review process.
The challenge
Ship features that reach into iOS and Android native code (sharing, files, widgets) fast, without slowing the rest of the team down.
What we shipped
- Native file-preview module
- Inbound and outbound share intent
- iOS widgets and an Android tile
- Design system
- New authentication flow
