Rebuilding Easy Banking

What made it hard

Rebuild a banking app that enormous numbers of people use, without ever pausing the new features they were expecting — and pull a team of specialists out of their separate corners while doing it.

What I did

  • Led the full rebuild of the Easy Banking app, from the first designs through to the version on people’s phones.

  • Moved the whole app onto a new interface so every screen looked and behaved consistently, rather than like ten apps stitched together.

  • Built features people use constantly: the money-management tools, international transfers, and Wero.

  • Set the technical direction for something that had to keep standing for years, not just until the next deadline.

  • Coached the team — pairing daily, and getting specialists to share what they knew instead of being the only person who understood one part.

  • Later moved to the server-side team and helped them adopt a new language without disrupting anything already running.

What came out of it

A rebuilt banking app on a modern foundation, one consistent interface across the whole thing, and a team that could keep it moving after I left.

  • Kotlin
  • Jetpack Compose
  • Material 3
  • Kotlin Multiplatform
