I will anon key supabase audit muse code productionize cursor ai app database security
Doxa S.
About this gig
Built in a weekend. Leaked in 30 seconds.
If your vibe coded app has RLS disabled, anyone can copy the Supabase key from your site and download your entire user list. No password. No hacking.
Lovable, Bolt, Base44, Replit, Cursor and Claude Code are great for speed, but they often skip database rules and leave a service_role key in the browser. It works, so nobody checks. That's how a Supabase data leak happens, and most founders find out from a customer.
I'm a senior full-stack engineer who fixes AI-built apps so they're safe to launch.
How I secure your app:
- Supabase lockdown: RLS enabled on every table, policies tested with your anon key like an attacker would, exposed service_role keys removed and rotated.
- Code audit: I break the Cursor and Claude Code bug loops eating your token budget and fix auth that only hides in React.
- Production migration: off the builder's sandbox to Vercel, Neon or AWS with CI/CD and automated backups.
You get a written report of what was exposed and what I fixed.
Stack: Next.js, React, TypeScript, PostgreSQL, Supabase, Prisma/Drizzle, OpenAI and Claude APIs.
Message me what you built it on and I'll tell you where I'd check first.

Anyone can open DevTools on your app and copy your Supabase key. If your RLS is wrong, they can download every user you have. Most Lovable, Bolt, Base44, Replit and Cursor apps ship that way.
I lock it down and make it production ready. Supabase security audits, RLS policies, exposed API keys, auth loops, edge functions, Stripe webhooks and white screen deploys on Vercel.
You get a diagnosis in hours, a permanent fix, a screen recording proving it and a plain English report.

FAQ
What does a Cursor AI rescue engineer actually do?
A Cursor AI rescue engineer steps in when your prompt-generated application breaks. I analyze your repository, fix brittle vibe coding logic loops, resolve technical debt, and transform your fragile prototype into a stable, market-ready software application.
Why do apps built with Lovable, Bolt.new, or v0 fail in production?
While tools like Lovable, v0, and Bolt.new build beautiful frontends quickly, they lack full system context. They frequently generate hidden security leaks, weak database schemas, and unhandled API edge cases that crash under real-world concurrent user traffic.
What is included in your full technical code audit?
My comprehensive code audit thoroughly inspects your application's architecture. I look for deep logical bugs, insecure environment variables, unhandled OpenAI API cost loops, duplicate function calls, and critical back-end vulnerabilities that endanger user information.
How do you transition a fragile MVP to production hosting?
I execute a seamless cloud infrastructure migration. I move your files off hobby-tier servers to scalable architectures like Vercel, Supabase, Neon, or AWS, establishing automated GitHub Actions, CI/CD pipelines, staging setups, and secure backup routines.
Can you fix broken webhooks and LLM API cost spikes?
Yes, I specialize in stabilizing backend middleware. I implement strict rate-limiting, error fallbacks, and resilient webhook event retry queues, ensuring your OpenAI or WhatsApp API integrations do not trigger accidental billing spikes or drop essential customer data.
Do you sign non-disclosure agreements (NDAs) to protect my codebase?
Absolutely. Protecting your proprietary intellectual property and data privacy is my top priority. I am completely comfortable signing an NDA before you grant access to your repository, ensuring your startup's code remains completely secure.
Can you package my responsive web app into a mobile application?
Yes. Through custom milestones, I can seamlessly wrap your production-hardened web app codebase using hybrid frameworks like Capacitor or Cordova, preparing your platform to successfully pass review processes for the Apple App Store and Google Play Store.
