FAQ
What information do you need to start fixing my app?
Share your Flutter project files (or GitHub repo), a description of the bug, and any error messages or screenshots. The more detail you give, the faster I can fix it.
What if you can't fix the bug?
If I determine a bug is beyond the scope of the package or unfixable without a full rebuild, I'll tell you before starting — and you won't be charged.
Do you fix bugs in apps you didn't build?
Yes, that's most of my bug fix work. I regularly fix and optimize Flutter apps built by other developers. Just share the source code and I'll get started.
What types of Flutter bugs can you fix?
Crashes, ANR errors, UI glitches, Firebase issues, API failures, login/auth bugs, Gradle errors, payment failures, memory leaks, and state management problems (Bloc, Provider, GetX, Riverpod).
How quickly can you fix my app?
Most simple fixes are done within 1–2 days. Complex bugs or larger packages (7–12 fixes) take 4–7 days. Message me with your issue and I'll give you an honest timeline upfront.

I will consistently come back to work with Mutie because he takes the time to understand the total scope. He ensures he understands the features and project at it's entirety before jumping in. This means whenever he delivers his work it always aligns with what we agreed on and the project vision.
