0-to-1 · Offline-first · Privacy by design · End-to-end ownership

I build mobile products from zero to shipped, and own every step in between.

Mobile engineer with 13 years on Android and iOS, owning products end to end. Most recently I designed and built HelperBook, a fully offline household-payroll app, and shipped it on Google Play.

How I can help

For founders and product teams who need a mobile app built, rescued or moved to shared code.

  • MVP build

    Take an idea to an app in the store. Native Android, Kotlin Multiplatform or React Native, chosen for your product and team rather than my preference.

  • Offline-first apps

    Apps that keep working with no signal and never lose what people entered: the phone as the source of truth, and sync designed with your backend team rather than bolted on.

  • App rescue and modernisation

    For apps that have become hard to change or release. Stabilise first, then modernise in steps you can ship.

  • Kotlin Multiplatform migration

    Start sharing code between Android and iOS with a Kotlin Multiplatform data layer, the way HelperBook does, then grow it one module at a time.

  • Fractional mobile lead

    Part-time ownership of your mobile side when you need senior judgement but not a full-time hire yet.
