About this Gig
Your app is crashing. Users are leaving. You've been staring at the same stack trace for days.
I fix Flutter problems fast, clean, and with a full explanation of what went wrong.
I've shipped 20+ Flutter apps in production and spent 3.5 years debugging real issues at scale. I reduced one client's processing time from 50 minutes to 5 minutes (86% faster) and cut infrastructure costs by 98% through root-cause fixes, not band-aids.
What I fix:
Crashes: null safety, state errors, async issues
UI jank, frame drops, rendering glitches
Memory leaks and excessive RAM usage
Slow lists, heavy screens, long load times
Firebase, API, and auth flow failures
Android/iOS platform-specific bugs
Build and release pipeline failures
Every fix comes with a written report: what broke, why, and what changed.
What I need: your repo link, crash logs, and a description of the issue.
Message me first I'll confirm I can fix it within 30 minutes.
