Experience

High-scale Project | The Royal Bank of Scotland

https://apps.apple.com/gb/app/coutts/id1534159074

The project was implemented from scratch by a team of 80+ people from the Customer Success department at Backbase. This high-scale project included various business features, so the development took almost two years from its inception to release.

I led an iOS subbranch in one of the four squads, synchronizing people to achieve the best performance. I also interviewed and hired new people for the iOS team and mentored some of them.
