Android Engineer (m/w/d)

Our client, a swedish fintech company in the payment sector, is looking for external support in the Android development.

Our client is starting a new project from scratch, this project is to be the V2 of a feature that is already in production. Some of the challenges are:
- The development of the feature won't stop, meaning the new project will be developed in parallel (synching both of them will be a challenge).
- And there is no documentation, great part of the work is understanding the business logic through the code (android, iOS, react native(js/ts)) and recreating it in the new project

Tasks:
- Support the team by maintaining its legacy features
- Support with the creation of new features
- Write documentation
- Be part of the testing process
- Help with architecture decisions
