After purchase, we confirm the agreed scope, your user and tenant model, and the questions to answer. NDA and restricted access arrangements come before the review.
Supabase Security Audit & AI Code Review
Supabase security audit for AI-built apps.
Review the data boundaries.
AI-built and vibe-coded apps often move quickly on Supabase. I independently review RLS policies, tenant isolation, Auth, Storage, Edge Functions and privileged-key handling, then recommend what your team should address before real customer data depends on those boundaries.

01 / The assessment
A Supabase security audit for AI-built and vibe-coded apps.
This Supabase security and AI code review examines whether grants, RLS policies and application access paths match your intended permissions. I review the available evidence for user and tenant isolation, privileged operations and file access, then separate material risks from checks your team still needs to perform.
Review areas within the agreed scope
- 01RLS coverage on exposed tables
- 02SELECT, INSERT, UPDATE and DELETE policies
- 03Cross-user and cross-tenant isolation
- 04Authentication and role boundaries
- 05service_role and privileged key usage
- 06Storage buckets and file policies
- 07Edge Functions, JWT and API validation
- 08Schema, migrations, backups and operations

02 / How it works
Purchase your audit. Know the next steps.
Assess
I review the agreed code, configuration and existing evidence using read-only access or sanitized exports.
Prioritize
You get a direct report ordered by technical risk, business impact and remediation value.
Walk through
We walk through the findings and recommended actions. Your team decides, tests and implements any changes.
“RLS enabled is not the same as RLS correct.”
A pragmatic approach
Review tenant isolation, not just the RLS checkbox.
A policy can exist and still be wrong for your product. I review your intended ownership model, shared records, roles and privileged access paths, then prioritise the gaps that could expose another user's or tenant's data.
- Review tenant-isolation rules
- Identify privileged-key risks
- Review Storage and Edge Functions
- Identify verification your team should perform

About me
Experience matters more when code becomes cheap.
I’m based in Berlin, Germany and work with startups and product teams internationally. I’ve been building production software professionally since 2013, helping organizations move from early decisions to reliable systems, migrations, and healthier engineering processes.
I use AI extensively in my own work. The goal is not to slow down AI-assisted development. It is to add the architecture, verification and operational discipline that lets you keep moving quickly without losing control.
Common questions
Supabase security audits, RLS reviews and AI code reviews.
What does a Supabase security audit cover?
The agreed Supabase security audit scope may include RLS policies, grants, tenant boundaries, Auth, Storage, Edge Functions and application access paths. The key review covers legacy anon and service_role keys and newer publishable and secret keys, where used. You receive evidence, limitations and recommendations. This is a read-only advisory review, not implementation.
How do you review cross-user and cross-tenant access?
I review policies, access paths and existing test evidence against your intended user and tenant model. The standard audit does not create or alter records or run active exploitation tests. Where direct runtime verification is unavailable, the report states that limitation and recommends checks for your team.
Is this a penetration test or compliance certification?
No. It is a scoped, point-in-time advisory review, not a formal penetration test or compliance certification. It does not guarantee that every vulnerability is found, and does not include remediation or production changes.
