About this Gig
Do you have an existing Android app that needs new features, better performance, or a modern facelift? I'm a Senior Android Developer with close to a decade of experience building and maintaining production apps, including enterprise-grade platforms used across large deployments.
I can help you:
- Add new features or screens to your existing codebase
- - Upgrade outdated dependencies, SDKs, and Gradle/Kotlin versions
- - Migrate legacy Views-based UI to Jetpack Compose
- - Improve performance, stability, and battery/memory usage
- - Refactor messy code into a clean, maintainable architecture (MVVM/Clean Architecture)
- - Fix crashes, ANRs, and other technical debt while I'm in there
Whether you inherited a codebase from another developer or your own app just needs some love, I'll review it, give you an honest assessment, and improve it without breaking what already works.
Let's chat about your app before you order, so I can give you an accurate scope and timeline.

FAQ
Do I need to give you access to my codebase or Git repo?
Yes, please share read access to your repository (GitHub/GitLab/Bitbucket) or a zip of the project so I can review the code before quoting an accurate scope.
Will you break my app while adding new features?
No. I test thoroughly before delivery and keep changes isolated so existing functionality keeps working. For larger changes I recommend a staging build before going live.
My app was built by another developer. Can you still work on it?
Yes, I regularly take over existing Kotlin/Java codebases. I'll review the code first and flag anything that affects timeline or cost before starting.
