About this gig

Your AI-built app got you 90% of the way there. I handle the last 10%

the part that actually matters: broken auth, security holes, failed

deployments, database errors, and missing logic.


Most AI-generated code looks like it works but has hidden problems:

unprotected user data, broken edge cases, fragile deployments. I find

these before your users do.


What I fix:

Authentication & security issues

Database/backend errors (Supabase, Firebase)

Deployment failures (Vercel, Netlify, Railway)

Broken logic and state management

Payment integration (Stripe)


I don't just patch symptoms I fix root causes so the problem doesn't

come back. You get clean, documented, production-ready code.


Send me your project link or a screen recording of the issue and I'll

tell you honestly whether I can fix it before you pay anything.
