Our customer in Norway has been developing a football app, supporting Fantasy Premier League, which is a game based on the matches in Premier League. The app is collecting data from an open API from Fantasy Premier League, giving the users a live experience of the game.

The app is developed, but contains some issues/problems and are lacking some functions. The development company based in Poland lost its main developer and is unable to complete the app.

• Backend is written in node js
• The mobile app is written in react native with expo

The main problem was with the point calculation during matches which is the core of the app. Performance speed drops during the weekend - in testing worked fine, we weren't able to figure why.

Backend got a bit too complex and might need some refactoring - features were added and we need some senior dev to help us out.

These were main biggest bottlenecks
What we need is a senior developer (preferably Premier League/Fantasy interested) to:

• Fase 1:  Finalize app and add some functions
• Fase 2: implement further functions and ideas.

We do have all code placed in our GitHub account.
