Mobile App Maintenance & Ongoing SupportJulien .J
Keep your app fast, stable, and up to date — without the overhead of a full-time dev.
Apps don't stop needing attention after launch. OS updates break things. Dependencies get deprecated. Users find edge cases. I provide ongoing maintenance and support for Flutter, FlutterFlow, and KMP apps so you can focus on growing your business.
What I handle
Bug fixes & crash resolution — fast turnaround on production issues
OS & SDK updates — keep your app compatible with the latest iOS and Android versions
Dependency management — update packages, resolve conflicts, prevent security vulnerabilities
Performance monitoring — identify and fix bottlenecks before users notice
Feature iterations — small enhancements, UI tweaks, and A/B test implementations
Store compliance — handle policy changes from Google Play and the App Store
How it works
We agree on a monthly hour allocation. I stay available for quick fixes and planned iterations. You get a reliable dev partner without the cost of a full-time hire.
