About this Gig

Your app crashes and you have been staring at the same stack trace for two days.


Send me the bug. I reproduce it, find the actual cause, fix it, and tell you in plain language what was wrong. No vague "should be fine now" deliveries.


WHAT I FIX

Crashes on launch, on a specific screen, or only on some devices

UI that breaks on small screens, notches or tablets

State bugs: data that disappears, duplicates or refuses to refresh

API and network errors, timeouts, broken JSON parsing

Builds that fail or will not sign

Performance: janky scrolling, slow start-up, memory leaks


HOW IT WORKS

Send the bug and how to trigger it, plus your repo or build. I reproduce it first, because a fix for a bug nobody reproduced is a guess. Then I fix, test on both platforms and send you the diff with an explanation.


WHY ME

12+ years in mobile, 150+ apps shipped. I work in Flutter, Swift and Kotlin daily, so I am not learning your stack on your budget.


Send me the crash log before you order and I will tell you honestly whether it is a one-hour fix or a bigger problem.
