Android Engineering
Senior Android, pick the engagement that fits.
Three shapes: sole-senior lead on an existing product, cross-platform port from iOS / Rust / web, or modernisation alongside your team (Kotlin migration, MVVM, Compose, performance). Pick the one that matches where you are.
Three Android engagements
The shape that fits depends on where your Android product is today. Pick the closest one; the engagement-fit pages explain how each runs.
Branch 3 — Development & Modernization
Embed with your Android team
For teams that have an Android product and a working team already, but need a senior to land a specific modernisation. I slot in alongside your existing engineers, not as sole owner.
Kotlin Migration
Java → Kotlin conversion with idiomatic rewrites. Coroutines replacing AsyncTask and callbacks. Null safety and type system improvements throughout.
Architecture Modernisation
MVVM/MVI with Clean Architecture, Hilt dependency injection, and clear separation of concerns. Makes your codebase testable and your team productive.
Jetpack Compose
Incremental adoption of Compose alongside your existing XML views, proven approach used on apps with 10M+ users.
Performance & Stability
Profiling, memory leak resolution, UI jank elimination, and crash rate reduction. Measurable improvements to user experience.

Android Development FAQ
What Android stack do you work with?
Kotlin (Kotlin-first, Java migration included), Jetpack Compose, MVVM/MVI with Clean Architecture, Hilt for DI, Coroutines + Flow, Room, Retrofit. I also work with Rust via JNI for performance-critical layers.
Can you work with an existing codebase?
Yes, this is the most common scenario. I start with a technical audit to understand the current state, then propose an incremental migration path. No big-bang rewrites. I've modernised apps with 10M+ installs without breaking production.
Do you work solo or with existing teams?
Both. I can work independently on a scoped feature or refactor, or I can embed with your existing Android team, doing code reviews, pairing sessions, and architecture guidance alongside your developers.
What does a typical engagement look like?
It starts with a 2–4 hour paid technical audit. Then we agree on a scope, either a fixed deliverable (e.g. "migrate this module to Compose") or a monthly retainer (Builder plan, see /fractional-cto). I provide weekly status updates and async communication throughout.
Do you also handle the Play Store and release process?
Yes. I can set up CI/CD pipelines (GitHub Actions, Fastlane), manage signing configurations, and advise on staged rollouts and Play Console best practices.
Ready to modernise your Android app?
Start with a paid technical audit. I review your codebase and deliver a prioritised action plan, whether you hire me to execute it or not.
