About this Gig
Your Flutter app is broken and you need it working today.
I'm a Flutter developer with 5 apps live on Google Play and 3 on the App
Store. I fix the things that stall a build:
WHAT I FIX
- Crashes and ANRs you can't reproduce
- Null errors, state bugs, setState issues
- Layout overflow and rendering glitches
- Firebase auth, Firestore and storage failures
- iOS build errors, Gradle and Xcode config
- Broken API integration and JSON parsing
- FlutterFlow exports that won't compile
ALSO WORK ON
React Native, Expo, Supabase, Node.js backends
WHAT COUNTS AS ONE BUG
One reproducible issue with steps to reproduce. Three screens crashing
from the same root cause is one bug. Need a feature built instead?
Message me and I'll send a custom offer.
WHAT I NEED
Repo access or a zip, steps to reproduce, and the error log or a screen
recording.
HOW I WORK
You get the root cause, not just a patch a working build plus a short
explanation of what was actually wrong.
Send me the error before you order. I'll tell you straight whether it's
a 20-minute fix or a 2-day one.

FAQ
What counts as one bug?
One reproducible issue. If three screens crash from the same root cause, that's one bug. If you have three unrelated issues, that's Standard.
What if you can't reproduce it?
I'll tell you within a few hours and we'll work out what's different about your environment. I don't bill for time I can't turn into a fix.
Do you need access to my whole codebase?
Usually yes, or at least the affected modules. You can add me to a private repo and remove me after. I never need your Play or Apple account.
Can you build a feature instead?
That's different work. Message me and I'll quote it as a custom offer.
What if the fix breaks something else?
Revisions cover that. I test the affected flow before delivering.
Do you work on FlutterFlow exports?
Yes, that's a big part of what I do here.
My app is React Native, not Flutter — can you help?
Yes, React Native and Expo both.
