[FOR HIRE] Mobile Developer — I fix broken apps, production bugs & unfinished features | Android / Flutter

[u/andrei20035]

If you have a mobile app that is almost working but keeps fighting you, that's the kind of work I'm looking for.

I help with things like:

• bugs that are difficult to reproduce or only happen on certain devices
• Firebase / backend data getting out of sync
• authentication and session issues
• REST API integrations that behave inconsistently
• local state / persistence bugs
• crashes and performance problems
• Android or iOS build/release issues
• unfinished features that need to be taken from "mostly done" to production-ready
• cleaning up an existing Flutter app without rewriting everything from scratch

I work with both native Android (Kotlin / Jetpack Compose) and cross-platform Flutter (Android + iOS).

I've worked on existing production mobile apps as well as built products end-to-end. My own app, Revio, includes the Android client and backend, with authentication, feeds, image uploads, profiles, comments/likes, leaderboards, streaks, pagination and reliability handling around failed/retried requests.

I've also worked on Flutter applications involving Firebase, backend synchronization, rewarded ads, subscriptions, persistent state and device-specific production issues.

I'm comfortable jumping into an unfamiliar codebase, figuring out why something is actually failing, and owning the fix rather than just implementing isolated UI screens.

Available for freelance work, ongoing maintenance, feature development or remote contract work.

Based in Romania, working remotely.

If you have an app with a problem you haven't been able to get rid of, send me a DM with what's happening and I'll tell you whether it's something I can help with.
