Android

Android app development services built on 8+ years of Jetpack Compose and production releases.

I design, build, and ship native Android apps — from a blank repository to a live Google Play listing, and then stay on to maintain what ships. Android is where most of the last 8+ years of my work has happened, and it's the platform my process is built around first.

01What Android app development looks like here

Every Android build starts with the same question: what does this app need to be true a year from now, not just at launch? That shapes the architecture decisions — module boundaries, how state flows through the UI, what gets tested, what gets cached, and how releases roll out. The UI layer is Jetpack Compose; the data layer is typically Room or SQLDelight with a clean repository boundary; the app is wired for analytics and crash reporting from day one, not bolted on after the first bad release.

For products that also need iOS, the same Android-first architecture becomes the foundation for a Kotlin Multiplatform build later — the Kotlin Multiplatform development page linked below covers that path. But plenty of Android engagements stay Android-only, and that's a fine scope on its own.

02Jetpack Compose, done properly

Compose is the default UI toolkit for every Android build I take on now. Done well, it means state that is easy to reason about, previews that actually match the running app, and UI code that stays maintainable as screens multiply. Done poorly — which is common on apps migrated in a hurry — it means recomposition storms, state that lives in the wrong place, and a UI layer that is slower than the View system it replaced. Part of the value of hiring a senior Android developer is avoiding that second outcome.

03The kinds of Android engagements I take

Android work here splits roughly three ways, and the right one depends on where the product already is.

  • New Android app from scope to Google Play release — architecture, build, store submission, analytics and crash reporting wired in.
  • Senior implementation support inside an existing Android codebase and team — feature work, architecture cleanup, or unblocking a stalled release.
  • Migration and modernization — moving a View-based app to Jetpack Compose, or updating an aging codebase to current Android SDK and Kotlin versions.

04Store releases and the parts people forget

Shipping an Android app is more than writing the code. Every build I release goes out with Play Console configured correctly, crash reporting and analytics wired in before launch (not added reactively after the first 1-star review), a release process that supports staged rollouts, and attention to Play Store policy so the app does not get rejected or suspended over something avoidable. This is the part of the process that separates "the app works on my device" from "the app is live and stable for real users."

05What proof looks like

Koru and Drinkist are both live Android apps I designed, built, and released end to end — real production apps with real users, not demos. The client work behind the testimonials below is largely Android: feature builds, integrations like AppsFlyer and deep linking, and Kotlin codebases handed to me mid-project.

Process

A direct path from first scope to production maintenance.

The workflow stays boring on purpose: define the target, make the technical decisions early, ship in visible increments, and keep the release path clean.

  1. 01

    Scope

    Turn a rough idea into a costed plan — features, milestones, and a realistic timeline.

  2. 02

    Architect

    Design a structure that stays maintainable as the product and the team grow.

  3. 03

    Build

    Ship production code — native Android, Kotlin Multiplatform, and Compose Multiplatform.

  4. 04

    Ship

    Release to the App Store and Google Play with analytics and crash reporting in place.

  5. 05

    Maintain

    Stay on after launch for fixes, OS updates, and the next round of features.

FAQ

The practical questions for this kind of work.

Do you build with Jetpack Compose or the older View system?
Jetpack Compose by default for new work. For an existing View-based codebase, I can extend it as-is or plan an incremental Compose migration — a full rewrite is rarely the right first move.
Can you take over an Android codebase someone else started?
Yes, and it is a regular part of the work — several of the testimonials below are from exactly this kind of engagement. The first step is always a short architecture review before committing to a timeline, so estimates reflect the real state of the code.
Do you handle the Google Play release yourself?
Yes — Play Console setup, staged rollouts, and policy compliance are part of the engagement, not a separate hand-off. The goal is a release that stays live, not just one that gets approved once.
What if the app also needs iOS eventually?
If iOS is on the roadmap, I structure the Android build so the data and business-logic layers can become a shared Kotlin Multiplatform module later, instead of a from-scratch iOS rewrite. The Kotlin Multiplatform development page on this site explains how that works.
How is Android work priced?
Hourly or fixed-price per milestone, with a retainer option for ongoing maintenance after launch. Send a short scope and I will recommend the structure that fits.
