You will get a Supabase backend with schema, auth, and RLS designed for production.
Project details
I build Supabase backends and PostgreSQL schemas that hold up in production: proper row-level security, append-only audit logs where you need them, multi-tenant isolation, and Edge Functions that enforce rules at the database level instead of trusting the app.
Currently running a live ISO 22000 compliance system on Supabase for a food manufacturer, with forward and backward batch traceability and four-eyes corrective action closure enforced in the database.
What you get in every tier: schema designed as a controlled document (numbered migrations, no ad-hoc changes), RLS policies that match your real access model, and short runbook docs so you can safely extend the schema later.
Two rounds of revisions in every tier. Free fixes for two weeks if something breaks because of my build.

About Vaughn
n8n & Claude AI Automation Architect | Supabase Backend Systems
Hillcrest, South Africa - 5:18 am local time
Most of my work falls into three buckets:
- n8n builds. Single workflow up to full multi-workflow systems with proper error handling, retries, and monitoring.
- Claude API and Claude Code work. Classification, routing, content generation, agent systems that ship to real users.
- Supabase backend and schema. Multi-tenant, row-level security, Edge Functions, audit logging done properly so you can defend it in an audit.
What I'm building right now: a live ISO 22000 compliance and traceability system for an African food manufacturer. It runs on the factory floor and is what unlocks EU export for them.
I'm South Africa's official n8n Ambassador, work UK hours, and you can see the standard of work I deliver from the portfolio below. If you've got a brief, send it. If I'm not the right person, I'll tell you who is.

Schema design call
We map your data model: entities, relationships, who can read and write what. I send back an ERD and migration plan for your sign-off.
Schema + RLS build
Migrations written and versioned. Row-level security policies set up so the database itself enforces access rules, not just the app layer.
