I will audit and fix security issues in your vibe coded or ai built app
Abhay Mittal
About this gig
Built your app with Lovable, Bolt, Replit, Cursor, or Claude Code and about to launch, take payments, or raise? I find and fix the security holes AI tools leave behind.
What I check:
- Supabase RLS policies, storage buckets, and service-role key exposure
- Auth and sessions (Supabase Auth, Clerk, Auth0, NextAuth, Firebase Auth)
- Roles: can a normal user reach admin pages or other users' data?
- API routes, server actions, and Edge Functions without auth checks
- Secrets in the frontend bundle, repo, or env files
- Stripe webhooks and plan limits that can be bypassed
- AI features: prompt injection, data leaks, runaway token costs
- Rate limiting, CORS, file uploads, vulnerable dependencies
What you get: a report ranked by severity in plain English, fixes as pull requests (Premium), and a re-test to confirm everything is closed.
5+ years building and fixing Next.js + Supabase apps, with 90+ client projects delivered.

I help founders ship AI-built apps that are secure and ready for real users.
I build and fix Next.js + Supabase SaaS products, add AI features (chatbots, RAG, AI agents), and run security reviews on apps made with Lovable, Bolt, Replit, Cursor, or Claude Code: open database tables, exposed keys, broken login and role checks, and prompt injection.
5+ years of full-stack and LLM work and 90+ client projects delivered. You get clear written updates, clean pull requests, and honest advice on what shouldn't be built.

FAQ
Do you need access to my code?
Yes. I need the live app URL, a test login for each user role, and read access to your repo. Code access is what lets me find issues a quick outside scan would miss.
Will you change my code?
Only in the Premium package, where fixes come as pull requests you review and merge. Basic and Standard give you the findings with clear fix steps your team can follow.
Which tools and stacks do you cover?
Apps built with Lovable, Bolt, Replit, Cursor, Claude Code, or by hand, on Next.js, React, Supabase, Firebase, Postgres, Clerk, Auth0, and Stripe. Message me if your stack isn't listed.
