I will audit debug and secure your ai built or vibe coded app
Vasili S
About this gig
Did you build your app with Lovable, Bolt, Cursor, v0, or another AI coding tool? It ships fast, but AI-generated code often hides real problems: missing Supabase Row Level Security, broken auth flows, secrets exposed in client-side code, and Stripe integrations that quietly fail in production.
I'm a full-stack engineer with 8+ years of experience, including running engineering as a startup CTO, with deep hands-on work in Next.js, Supabase, and Stripe. I read through your codebase the way I'd review a teammate's pull request: line by line, checking what actually happens when a real user, or someone malicious, hits your app.
What I check: Supabase Row Level Security policies and auth rules, secrets or API keys exposed in the client, Stripe checkout/subscriptions/webhook reliability, core bugs affecting everyday use, and database schema or query issues.
Every order includes a clear written report of what I find. On Standard and Premium, I fix the issues myself and hand back a working, secured app, not just a list of problems.
Not sure which package fits? Message me with a link to your repo or a quick description of your stack before ordering.

Roots in ACM competitive programming — precise, tested code. Send your project — I'll tell you honestly if and how fast I can help.

FAQ
Who owns the code and fixes after delivery?
You get full ownership of every fix and any code I write. Nothing is licensed or shared with other clients.
Do I need to give you access to my Supabase and Stripe accounts?
Yes, I'll need read access to review your setup, and write access on Standard/Premium to apply fixes. I only touch what's needed for the audit.
Can you deploy the fixes directly to my own Vercel and Supabase project?
Yes, everything stays in your own infrastructure. I work directly in your repo and your Supabase/Vercel projects, nothing is hosted or stored on my side.
What if you find more issues than the package covers?
I'll flag everything in the report and tell you clearly what's in scope versus what needs a custom offer, so there are never surprise charges.
