You will get your Supabase auth and RLS set up for a secure multi-tenant SaaS
Top Rated
Project details
Weak row-level security is the most common way a multi-tenant SaaS leaks one customer's data to another, and you usually find out from the customer. I make sure that cannot happen on your Supabase setup.
I set up or review your auth and RLS policies, confirm every table enforces tenant isolation, and fix the gaps I find. From the Standard tier up, you get a written audit in plain language: what was wrong, why it mattered, and what I changed. On the top tier I add a test suite that proves one tenant cannot read another's data, so it stays safe as you keep building.
I work carefully in your live project and explain every change, so nothing is a black box.
Before I start, I write the exact deliverable and acceptance criteria into the order. If the finished work does not meet that scope, I revise until it does or you do not pay.

Senior Next.js dev to fix Supabase RLS + multi-tenant data leak
Furqan is a sharp full-stack developer who fixed a nasty multi-tenant data leak in our Next.js and Supabase app. Tracked the RLS issue down to the real root cause, fixed the row-level security properly, and sanity-checked the rest of our auth flow while he was in there. Careful work on a live production app, clear explanations, and genuinely good security instincts. Highly recommended.

Job Success
Faisalabad, Pakistan - 12:10 am local time
6+ years full-stack, Top Rated, 100% Job Success. I work AI-native with Claude Code and Cursor every day, so I ship production code fast and clean up messy code faster.
WHAT I BUILD
- AI integration and LLM features: OpenAI API, Claude API, Gemini, RAG with vector search (pgvector), AI chatbots, AI agents, tool calling and agentic workflows
- MCP servers and integrations so your product can plug into Claude, ChatGPT and other AI tools, or expose your own data and actions to LLMs
- Full-stack SaaS web apps in Next.js (App Router), React, TypeScript, Node.js, Tailwind and shadcn/ui, deployed on Vercel
- Supabase and PostgreSQL backend: auth, row-level security, multi-tenant SaaS architecture, edge functions and realtime
- Stripe billing done right: subscriptions, webhooks, metered and usage-based plans
- SaaS MVP builds from spec to launch, usually 3 to 6 weeks for a first working version
- Taking over an existing build: audit, stabilize, then extend with AI
TAKING OVER AN EXISTING CODEBASE
A lot of my work is inheriting a Next.js or Supabase app someone else started. I audit what's there and tell you the honest state of it. I ship a few low-risk quick wins first so you see progress and I earn trust. Then I fix the fragile parts, and only then add new AI features. The rule the whole time: don't break what's live.
SOME OF MY RECENT WORK
- Multi-tenant hospitality SaaS for a German client, 58 interconnected subsystems, live with paying restaurant customers
- Autonomous AI content-agent platform with Stripe subscriptions, running unattended for paying users
- AI document intake tool with automated extraction, cut manual data entry from hours to minutes per batch (Loom walkthrough available)
- AI scraping and lead-enrichment pipelines with LLM classification
HOW I WORK
I take ownership and ship without hand-holding. I communicate clearly and often, and I don't go quiet. Nothing risky goes to production without a rollback plan. Most clients start with one project and keep me on long term.
MY GUARANTEE
We scope a clear first milestone. If I don't deliver it to the spec we agreed, you don't pay for it. That takes the risk of hiring an unknown off your side of the table.
Tell me what you're building and where it's stuck, and I'll tell you honestly whether I'm the right person for it.
