Android app maintenance and evolutives with production criteria

Fixes, improvements, QA, API integration and releases for existing mobile apps that need to keep moving.

I can take over an app built by another supplier.
Prioritized backlog, fixes and evolutives.
QA, publication and release notes.

Experience with field Android apps and existing systems

For MaderaPlus +DERA I diagnosed an Android Java app with offline sync, backend and a legacy website. The case documents the diagnostic; Kotlin/KMP are evolution recommendations.

Review the case and delivered scope

Diagnostic staging with anonymised data.

203 documented backend/API calls.

115 issues reviewed and 23 prioritised actions.

Common maintenance needs

To start, I need repository access, a reproducible environment, publication context and someone who can validate changes.

Recurring errors

Bugs, regressions or fragile behavior in important application flows.

Evolutives

New functionality, API changes, UX improvements or product adaptations.

Release and publication

Version preparation, risk review and support through the production release.

How work is ordered

Continuity needs a simple operating frame so every request does not become an emergency.

Initial diagnostic

Reproducible build, application state, dependencies, visible debt, publishing access and critical flows.

Priorities

Backlog, validation owner and criteria to separate urgent fixes from planned improvements.

Follow-through

Small deliveries, tests, change notes and clear release and rollback criteria.

Common Questions

The minimum worth clarifying before opening a collaboration.

Can you maintain an app you did not build?+

Yes, when repository access, a reproducible environment, minimum context and a validation owner are available.

Is this a retainer or a fixed project?+

It can be a retainer for recurring work or a fixed project for a specific release or evolutive.

Do you also review publication?+

Yes. I can cover the checklist, tests, risk closure, release notes and publication support.
