App Modernization & Migration

If you're maintaining two aging native apps — or one that's grown brittle — I migrate them to a single, modern Flutter architecture, without stopping your releases.

From legacy to unified

Separate iOS and Android codebases mean double the work and drift between platforms. I consolidate them into one Flutter codebase with clean architecture, so features ship once and behave the same everywhere.

Zero-downtime migration

Migrations are done incrementally — feature by feature, with the old and new coexisting where needed — so users never see a broken release and the business keeps shipping throughout.

Proof

I've repaired and modernised large codebases — including a 235-file client with hundreds of broken imports brought back to zero unresolved — and kept fleets of apps at 99.9% uptime through the transition.

FAQ

Do we have to stop releasing during a migration?

No. I migrate incrementally so you keep shipping. The old and new can run side by side until the switch is safe.

Why migrate to Flutter?

One codebase instead of two means faster features, consistent behaviour across platforms, and materially lower maintenance cost.

Can you rescue a stalled or broken codebase?

Yes — stabilising inherited, broken, or half-finished codebases and getting them shipping again is a large part of what I do.
