Gig Summary
About this gig
Your app is crashing, throwing ANR errors, or rejected by Google Play and you need it fixed at the root, not patched.
I'm Shahzaib: 620+ completed projects, a perfect 5.0 across 275+ reviews, most of them apps other developers walked away from.
My specialty is diagnosis. I read your logcat, find the real cause, and fix it so the bug doesn't return in your next release.

Crashes, ANRs and force-close errors
Memory leaks, lag and slow performance
Google Play rejections and policy issues
Apps broken by new Android versions

FAQ
My app was rejected by Google Play. Can you fix that?
Yes — rejections for Target SDK/API updates, privacy issues, and crash-rate flags are among my most common jobs. Send the rejection email and I'll tell you exactly what's needed.
I built my app with AI (ChatGPT, Cursor, Lovable) and it's broken. Can you fix it?
Yes — this is increasingly common and nothing to be embarrassed about. I'll debug the generated code, fix what's broken, and clean up the structure so it's maintainable going forward.
A new Android version broke my app. Can you make it work again?
Yes, this is my specialty. I'll update your code for current Android versions while keeping backward compatibility.
I only have the APK, not the source code. Can you still help?
Often, yes — I've rescued several APK-only apps. Message me first so I can assess honestly before you order.
How fast can you fix a critical crash?
Basic delivers in 48 hours; with the 24-hour extra, urgent production crashes are often same-day. Send your log and I'll give you a realistic time upfront.
Will the same bug come back?
That's exactly what I prevent — I fix root causes, not symptoms, and explain what was wrong so you understand your app better.
Do I get the source code back?
Always. Full updated source code with every order — never a black box.
The developer who built my app disappeared. Can you take over?
Very common. Send what you have and I'll take it from there — no judgment about the old code.
Do you fix Flutter and React Native apps, or only native Android?
Both. Native Android in Kotlin and Java is my main work, but I also fix Flutter and React Native apps, including build failures, plugin conflicts and platform-specific crashes.
