A prioritised improvement plan
A review of the agreed repository areas, build setup and user flows. Findings distinguish urgent defects, maintenance risks and improvements that can wait.

Improve an existing app
A better app starts with a diagnosis.
A slow screen, recurring crash or difficult release can make every new feature feel expensive. The right response depends on where the problem lives. Rebuilding the entire app should be a considered decision, not the default answer to an unfamiliar codebase.
I work on existing Flutter products to understand the current architecture, reproduce the important problems and plan improvements in manageable stages. The aim is to preserve working behaviour while making the affected flows easier to use and the code easier to maintain.
A good fitFor teams inheriting a Flutter codebase, planning an upgrade, or dealing with recurring bugs, slow screens and inconsistent API behaviour.
Define it. Build it. Review it.
What we can deliver together.
The final deliverables depend on your product and the scope we agree.
Focused implementation
Bug fixes, state-management improvements, API handling or targeted refactoring. Each change is tied to a specific problem and an agreed acceptance check.
A repeatable release handover
Setup notes, changes made, verification results and remaining risks. Upgrade and release work includes the agreed regression checks and recovery plan.
A decision worth making early
Make the current build reproducible first.
Before a Flutter or dependency upgrade, establish which versions build today and which journeys must keep working. Sign-in, payments where present, notifications and platform integrations often need explicit regression checks. We agree that baseline before changing dependencies.
Performance work needs the same discipline. We reproduce the slow interaction on a relevant device, inspect its cause and compare the affected flow after the change. A narrower fix can be more valuable than a broad architectural rewrite with no clear customer benefit.

Scope, timing
and next steps.
01Can you take over an app built by another developer?+
Yes. An initial review checks repository access, build reproducibility, dependencies and the current problems. That provides a basis for a useful estimate and highlights anything missing from the previous handover.
02Will the app need a complete rewrite?+
That depends on the findings. Targeted fixes and incremental refactoring are often worth assessing first. If a rewrite is proposed, it should have a clear reason, a migration plan and an explanation of what existing behaviour must be preserved.
03Can we arrange ongoing Flutter maintenance?+
Yes, we can discuss a maintenance scope around your release schedule and expected changes. We agree the covered areas, response times and included work up front, so your team knows how fixes and future releases will be handled.
