Android App Rescue & Modernisation

Get your Android app moving again.

An app doesn’t have to be beyond repair to need outside help. Perhaps every release is difficult, a handover has left gaps, or the next feature keeps getting buried under old problems. I help teams understand the code they have and make a practical plan for improving it.

Where I can help

For teams taking over an unfamiliar app, maintaining a Java codebase or struggling to make changes with confidence.

Understand the problem

Review the codebase, build setup and release process with your team. Reproduce the blockers and separate urgent defects from longer-term maintenance work.

Stabilise the important paths

Agree which user journeys and failures matter most, then address them with focused implementation and appropriate regression checks.

Modernise in useful steps

Move Java code towards Kotlin, replace problematic dependencies or improve architecture around the features you are actually changing.

A manageable first step

A focused review is a useful first step when the scope is unclear. We agree which parts to inspect, discuss the findings and prioritise the work. From there I can implement changes with your team or take on an agreed piece of the recovery work.

Before we start

Does this mean a rewrite?

Not automatically. Existing behaviour, release constraints and the cost of maintaining a replacement all matter. A targeted change may be the better starting point.

Can you help after another developer leaves?

Yes. We can start with the repository, build instructions and known issues, identify the gaps and agree a manageable handover and implementation scope.

Can we start with a review only?

Yes. A review can be a standalone engagement. Its scope and expected outputs are agreed before work starts.

Tell me where you need help.

Tell me what the app does, what is blocking delivery and whether there is a deadline. Please leave credentials and customer data out of the initial email.
