About this Gig
Your Flutter app is broken. Send it to me.
Build failing after a Flutter upgrade. A crash you can't reproduce. A screen that works on Android and falls apart on iOS. A developer who stopped replying and left you a repository you can't read.
I fix other people's Flutter code. That's most of what I do.
WHAT I FIX
Crashes, freezes and memory leaks.
Build failures after Flutter or Xcode upgrades.
Deprecated packages and dependency conflicts.
Firebase issues: auth, Firestore rules, push notifications.
UI that breaks on one platform, screen size or device.
Slow scrolling, janky animations, oversized bundles.
App Store and Play Store rejections.
I ALSO ADD FEATURES
New screens in an existing codebase. Firebase or API integration into an app someone else wrote. Refactoring a codebase you inherited.
HOW TO ORDER
Message me first with your repository or a screen recording. I'll tell you which package covers it and what it will take, before you spend anything. If it's a five-minute fix, I'll say so.
NO SOURCE CODE?
Only have the app on the store? Message me anyway. Sometimes there's a way forward. I'll tell you honestly.

FAQ
What do you need from me to start?
Your repository (GitHub, GitLab or a zip) and a clear description of the problem, ideally a screen recording or the error text. The more precisely you describe when it happens, the faster I find it.
What if you can't fix it?
I look before you pay. Message me first and I'll assess it for free. If I can't fix it, I'll say so, and I can usually still tell you what is actually going wrong.
My app was built by someone else. Can you still work on it?
Yes, that is most of my maintenance work. I don't need the original developer's help, only the source code. Reading unfamiliar Flutter codebases is a normal part of the job.
Will you keep my code confidential?
Yes. I'm happy to sign an NDA before you share anything, and I delete project files once the work is delivered and accepted.
Can you publish the updated app to the stores?
Yes. Play Store and App Store re-submission is included in Feature Update and available as an extra on the other packages. You'll need to give me access to your developer accounts.
