About this gig
Did you build your MVP using Lovable, Bolt, or AI, only to realize your database might be completely exposed?
AI tools are incredible for building fast, but they routinely skip critical security protocols. If your Supabase Row-Level Security (RLS) is misconfigured, anyone with your public anon key can view, alter, or delete your users' sensitive data.
Whether you are a non-technical founder preparing to launch in, or a developer needing an expert double-check before a major compliance review, I am here to secure your stack.
What I will audit and fix for you:
- RLS & Policy Validation: I ensure every single table strictly enforces auth.uid() and prevents unauthorized global data access.
- Service Role Leak Prevention: I verify that your high-privilege service_role key is locked down tightly on the server side and never leaked to the client frontend.
- Lovable Architecture Review: I audit your Lovable workspace to ensure API tokens (Stripe, OpenAI) aren't leaked in chat history and that critical logic lives safely in Edge Functions.
- Remote Procedure Call (RPC) Testing: I check database functions to ensure they cannot be triggered by malicious public actors.

On October 30, Supabase stops auto-exposing new tables on every existing project. If Lovable, Bolt, v0, Cursor or Claude Code writes your migrations, your next feature ships broken with "permission denied."
I'm the Supabase and Postgres engineer who fixes what AI builders miss. Grants, RLS policies, security audits, exposed keys, auth, edge functions, pgvector RAG pipelines and MCP servers for AI agents, on Next.js and Vercel.

FAQ
Why does my AI-generated app need a Supabase security audit?
AI platforms prioritize building user interfaces quickly, but they regularly skip critical backend configurations. A Supabase security audit ensures that your automated code hasn't accidentally exposed your private database structure or left doors open for hackers.
Can't I just ask an AI tool to fix my Supabase RLS policies?
Large Language Models (LLMs) excel at making things work, not making them secure. If an AI encounters a database error, it will often disable Supabase RLS (Row-Level Security) entirely to bypass the issue, which instantly leaks your data to the public.
What happens if someone steals my public anon key?
By default, the anon key is safe to use in frontend code only if your database is locked down. If your backend lacks proper policies, anyone with that key can use browser developer tools to download, modify, or completely delete your data.
How do you fix a leaked service_role key during a backend audit?
The service_role key bypasses all security rules and must never touch the frontend. During my backend audit, I locate any exposed keys, regenerate them safely in your dashboard, and move administrative processes to secure environments.
What specific risks do you look for in a Lovable dev project?
When auditing a Lovable dev workspace, I inspect the prompt records to ensure secret API credentials weren't leaked in chat logs. I also verify that the platform's AI code successfully handles data manipulation through secure, server-side actions.
Do you write custom Supabase Row-Level Security rules from scratch?
Yes. In the Standard and Premium packages, I actively write and execute robust Supabase Row-Level Security logic. This ensures users can only access information matching their verified auth.uid().
Will this vibe coding troubleshooting break my app’s features?
Not at all. My vibe coding troubleshooting isolates your database layer from your frontend visual elements. I test your application rules in a safe staging configuration to guarantee your platform functions perfectly while remaining tightly secured.
Can you help my startup pass US or UK investor compliance?
es. If you choose the Premium package, I deliver a formalized technical compliance report. This document proves to venture capitalists and enterprise procurement teams that your application safely protects consumer information.
How do you secure database functions from automated bot abuse?
I run targeted RPC testing (Remote Procedure Calls) to verify that malicious actors cannot trigger your database functions externally. I also configure server-side rate limits to stop automated bots from driving up your platform bills.
Is it safe to share my database credentials for a backend audit?
bsolutely. You never need to hand over your master password. For a comprehensive backend audit, you simply invite my developer profile to your dashboard with restricted privileges, keeping your production environment completely safe.
