A secure messaging app for the public sector

What made it hard

Build messaging that works instantly, keeps working with no signal, and meets public-sector security requirements — while bringing the in-house developers onto tools most of them had not used.

What I did

  • Building a secure messaging app: messages arrive instantly, everything still works offline, and people can share photos and their live location.

  • Set up the release process — automated testing and distribution inside a closed environment, so nothing goes out unchecked.

  • Bringing the organisation’s own developers onto the toolset and coaching them through it.

  • Introduced the team to working with AI agents, and wrote the shared setup they use.

What came out of it

Under NDA, so the description above is deliberately general.

  • Kotlin Multiplatform
  • Compose Multiplatform
  • Automated testing
