You will get your broken code fixed in 24 hours - Flutter, Python, JS/TS or APIs
Project details
Your app crashes, your script throws errors, your build fails - and you need it working today, not next week.
I fix bugs fast, and I prove it before you release payment: every delivery includes a short screen recording of your code working.
WHAT I FIX
• Flutter/Dart app crashes, build errors, state bugs
• Python scripts, scrapers and automation that stopped working
• JavaScript/TypeScript errors, API integrations returning wrong data
• Backend issues: REST APIs, Cloudflare Workers, Supabase, Stripe webhooks
• CI/CD pipelines that suddenly went red
HOW IT WORKS
1. Send me the error message + code access (repo, zip or snippet)
2. I confirm the diagnosis and scope before starting
3. You get the fixed code + a video showing it working
4. Clean code, no hacks - I explain what was wrong and why
If I review your issue and determine I can't fix it, I tell you upfront and you don't pay. No wasted time on either side.
