HOW IT WORKS
- Message me with the error and a screenshot or repo
- I confirm scope, price and delivery before you order
- I fix it, test on Android and iOS, return clean code

- No half-fixes. Message me first and I'll tell you honestly if I can solve it.
FAQ
I don't know what's causing the bug — can you still help?
Yes, diagnosis is part of the job. Send the error log or a screen recording and I'll identify it before you order.
Can you work on someone else's code?
Yes. Most of my orders are existing codebases I've never seen. Send the repo or a zip.
Which package do I need?
Message me first. I'll look at the issue and tell you exactly which one fits, or send a custom offer.
Do you fix native Android/iOS too, or only Flutter?
Flutter is my specialty, including the native Android and iOS layers underneath it (Gradle, Kotlin, Xcode, Swift config, permissions). But I can help u in native also plz share more details.
My app was rejected by Apple — can you fix that?
Yes, that's the Premium package. I've handled store submissions and review rejections across seven live App Store apps.
