Freelance Android and Kotlin developer

I add features, integrate APIs and prepare Android app releases. I review the code and affected workflows before agreeing on scope and timing.

MaderaPlus: understand an app before changing it

The +DERA diagnosis covered an Android Java app with offline synchronisation, its backend and the existing website.

See the scope of the diagnosis

A reproducible environment and review of reported issues.

23 actionable items identified in the issue log and a phased roadmap.

Kotlin and KMP were proposed as future options; no migration was delivered.

Where specialist support helps

This page covers focused Android delivery; recurring maintenance has a separate offer.

Complex mobile feature

Implementation in an existing codebase, architecture, offline states, permissions or sensitive product flows.

Release under pressure

Technical QA, regression control and publication preparation when the cost of error is high.

SDKs and integrations

API contracts, examples and documentation for the teams integrating your SDK.

What is delivered

The agreed app changes, tests and release notes for your product or engineering team to review.

Implementation

Features, fixes, backend integration or adaptation to the existing application architecture.

Stabilization

Contract and regression tests, a review of outstanding risks and checks before release.

Continuity

Decisions, tests, pending items and publication criteria documented for the next stage.

How we scope Android work

The initial review separates the requested change from risks in the existing app.

Codebase and dependencies

Android version, modules, SDKs and affected services. We establish what can be built and tested before committing.

Change validation

Main flow, permissions, errors and offline conditions where included in scope.

Release and handover

A verifiable build, change notes and publication steps. Store approval depends on its review.

Tell me about the project

Tell me what needs to be resolved.

Objective, current state and timing are enough to assess fit and suggest a concrete starting point.

A human reply, normally within one business day. No automatic addition to marketing lists.

Service enquiry for companies, agencies and consultancies; this is not a job opening.

What context are you writing from?
A few lines about the project are enough.
Add more informationCompany, budget and timing, if you know them.
Data used and how to withdraw consent

I agree that Google Ads may measure this enquiry using its submission ID, date, my normalized email address transformed with SHA-256 and, when one exists and remains current, the click identifier. This is optional, does not enable remarketing and can be withdrawn using the contact details in the privacy policy.

Anti-spam verification

It will load when you start completing the form.

Usual reply within one business day.

Common questions

Can you work on an app for just a few weeks?+

Yes. A short sprint can cover a blocker, release or stabilisation work if we can define the scope.

Do you work with agencies that deliver apps?+

Yes. I can provide mobile development under your brand or join client-facing work when appropriate.

Can you also work on the backend or integrations?+

Yes. Mobile work often involves APIs, contracts, SDKs and the data flows they depend on.
