I will build a secure supabase backend with rls and auth
Suleyman
About this gig
Your app is only as safe as its backend. I build Supabase backends that are secure by default not an afterthought.
Most backends leak data because the database trusts the client. I do the opposite: default-deny Row Level Security, server-side validation, and proper auth. Your data stays yours.
WHAT YOU GET
- Clean PostgreSQL schema designed for your app
- Row Level Security policies (tenant and role isolation)
- Authentication: email, roles, and MFA on request
- Edge functions for server-side logic
- Storage, audit logging, and API on higher tiers
- Full source code, tested before delivery
WHY ME
I build and run multi-tenant production systems daily real apps used by real businesses, not demos. Backend and security is what I do best.
HOW IT WORKS
1. You tell me what your app needs
2. I design the schema and security model
3. I build, test, and hand over clean, documented code
Not sure which package fits? Message me first I will tell you honestly, even if the answer is that you need less than you think.

I build secure backends and full-stack apps, fast.
This year I shipped production systems: a multi-tenant SaaS CRM my own company uses daily (Supabase, React, RLS, MFA, GDPR export) and an e-commerce price and SEO tracking platform (Next.js, Supabase).
What I do:
- Supabase and PostgreSQL: schema, RLS, edge functions, auth
- Full-stack web: Astro, React, Next.js, Cloudflare Workers
- Automation and data: pipelines, scheduled jobs, price monitoring, reporting
Security done right: default-deny, server-side validation.

FAQ
I already have a Supabase project. Can you work on it?
Yes. I can work on your existing project or start a fresh one. Just add me as a member or share access, and I will build on what you have.
Do I need to know SQL or backend stuff?
No. You tell me what your app does and what data it holds. I design the schema, security, and auth. You get clean code and a short guide on how to use it.
Will my data be secure?
That is the whole point. I use default-deny Row Level Security, so the database blocks everything unless a policy allows it. No accidental data leaks from the client side.
What do you need from me to start?
A short description of your app, the main things users do, and any existing project or design. We sort out the details in chat before I begin.
