Hire a Supabase Developer
Who Gets RLS Right
Supabase lets you move fast because the database is right there in the browser. That speed is also the risk — Row Level Security, auth, and schema design are where apps quietly break or leak. We build them properly, on a stack we run in production.
A Supabase developer builds your app on Postgres with Row Level Security, auth, realtime, storage, and edge functions — the pieces that make Supabase fast to build on and easy to get wrong. We ship production apps on this stack and join existing projects to fix or extend them. Code and project stay yours.
The full Supabase stack, in production
Row Level Security
Policies written and tested per table so users reach only their own data — the part that most often ships wide open, done right first.
Postgres schema & migrations
A data model that stays correct as you grow — proper relations, constraints, indexes, and versioned migrations, not ad-hoc tables.
Auth & sessions
Email, OAuth, Apple/Google sign-in, and session handling that actually holds — built on Supabase Auth, integrated with your app.
Realtime
Live updates, presence, and subscriptions where your product needs them — without hammering the database or leaking data.
Edge functions
Server-side logic for the things that must not live in the browser — secrets, webhooks, and privileged operations.
Storage & integrations
File storage with correct access policies, plus Stripe, external APIs, and AI/LLM features wired in cleanly.
How we get Row Level Security right
Supabase is fast because your database is reachable straight from the browser — and risky for the same reason. Row Level Security ships disabled by default: every table is readable by anyone with your public key until you turn it on and write a policy. Miss one table and it's world-readable. In 2025 that became its own vulnerability — CVE-2025-48757 — after missing RLS exposed data across 170+ AI-generated apps. Here's how we make sure it never happens to yours.
Enable RLS on every table, deny by default
No table ships with RLS off. The starting position denies everything; we then open exactly what each role needs — nothing more.
Write policies per table, scoped to the user
Each policy ties rows to the authenticated user or their tenant, using (select auth.uid()) so it stays fast instead of re-running per row.
Keep the service_role key server-side
The service_role key bypasses RLS entirely, so it never touches the browser — privileged work runs in edge functions, not client code.
Test as a real user, and as an attacker
We verify policies signed in as one user reaching for another's data, across tenants, and anonymously with just the public key — the boundary is proven, not assumed.
We ship real products on Supabase
Not a first project on the stack. We run live apps on Supabase with full Row Level Security, storage, auth, and Stripe — and we've rebuilt the permission layer of an AI-built app whose data was wide open. RLS is the first thing we get right because it's the first thing we see go wrong.
