Shipped new features for an app used by 17 million users across the UK and Europe having 100k train tickets sold every day.

Worked within a team of 20 developers split between two offices: Paris and London. I have worked on different aspects of the European and UK app: enabling new carries such as Flixbus coaches, preparing the apps for iOS 11 and iPhone X and working on the convergence of both apps towards one single app by updating API endpoints and getting rid of legacy code both in Swift and Objective-C. Have also worked on implementing complex fare requirements with client-side and server-side business logic.
