I will rescue your ai broken store or website


About this gig
Did an AI tool or "vibe-coding" build you a store that looks done but breaks in production 500 errors, broken checkout, payments that don't complete, security holes? I fix what the AI got wrong.
I'm a senior full-stack engineer (6+ yrs, 125k+ lines of production WooCommerce/PHP) who runs a real store at 120-150K visits/month. I've spent my career on exactly the parts AI gets wrong: payments, concurrency, security, data integrity.
WHAT I FIX
- 500 errors / white screens in production
- Broken or failing checkout & payments
- Orders that don't save or don't mark paid
- Security holes (exposed keys, injection, no validation)
- Data saving wrong or not at all
- Code no one can safely change
HOW IT WORKS
- Send the error or broken flow + access
- I reproduce it and find the real cause
- I fix it, harden it, and prove it works live
WooCommerce, Shopify, WordPress, custom PHP/Node/React.
For a bigger rebuild, message me I'll scope it and send a custom offer.
Send the exact error + a link/screenshot and I'll tell you straight if I can fix it.
