Working for the biggest train ticket company in Europe

Shipping 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.
