About this Gig
Are you stuck with a broken Flutter app that another developer left unfinished, crashing, or rejected from the App Store or Play Store? I take over existing Flutter and Firebase codebases, find the real problem, and fix it without forcing an unnecessary rebuild.
WHAT I OFFER:
- Full audit of your existing Flutter/Firebase codebase
- Fix build failures and dependency conflicts
- Resolve app crashes and unstable features
- Fix Firebase Auth, Firestore, FCM, and Storage bugs
- Diagnose and resolve App Store rejection issues
- Fix Google Play rejection and policy compliance issues
- Correct signing, certificates, and package/bundle ID errors
- Fix broken API and backend integrations
- Clean up messy or undocumented inherited code
- Resubmit your app for store approval
I don't push for a full rebuild unless it's genuinely needed. Most inherited apps just need targeted fixes. Message me before ordering with your issue (crash log, rejection email, or short description) so I can scope it right.
FAQ
1. My app was built by another developer and I don't have full documentation, can you still work on it?
Yes. Most of my work is exactly this, taking over undocumented or half-finished codebases. I start with an audit to map out what exists before touching anything.
2. Do you need my app to be rebuilt, or can you just fix what's broken?
In most cases, no rebuild needed. I only recommend rebuilding a section if patching it would take longer or cost more than redoing it, and I'll tell you upfront if that's the case.
3. What do you need from me to get started?
Access to your GitHub/source code repo, Firebase project (if used), and details on the specific issue, crash logs, rejection email from Apple/Google, or a description of the bug.
4. Can you handle both iOS and Android store rejections?
Yes, I handle App Store (Apple) and Google Play rejection issues, including signing, certificates, permissions, and metadata/policy fixes.
5. What if the audit finds more issues than expected?
I'll send you a clear breakdown with priority levels before doing any paid fix work, so you decide what to tackle and what to skip.
