Project details

Your SaaS is growing, but single-tenant architecture won't scale. I design multi-tenant systems that keep data isolated while handling thousands of customers.

Most platforms hit a wall at 50 users. Queries slow. Security risks multiply. I solve that upfront.

𝐖𝐡𝐚𝐭 𝐲𝐨𝐮 𝐠𝐞𝐭:
• True data isolation – PostgreSQL RLS or MongoDB tenant keys
• Tenant-aware routing – requests stay in the right sandbox
• Auth scoped to tenants – users never see other orgs' data
• Admin portal to manage tenants and monitor usage
• Production-ready code your team can maintain

𝐖𝐡𝐲 𝐦𝐞:
• 60+ apps delivered – scaled from 10 to 10,000 users
• Database expert – PostgreSQL, MongoDB, Supabase, Prisma
• Security-first – isolation validated at every layer
• Retrofit experience – add multi-tenant to existing code
• 100% Job Success, top-rated plus

New build or retrofit – I deliver architecture that scales without the rewrite.

100% Job Success

Lahore, Pakistan - 11:01 am local time

I'm a Next.js & NestJS SaaS developer. Cut a client's AI costs by 75%, pushed another's Lighthouse 38 → 91 & they said: "revenue went up." I build full-stack SaaS with GraphQL, REST, Supabase and RAG.

Give me your Next.js, NestJS project or SaaS idea and I'll build it so it works in production, not just in demo. That's my promise.

If you send me an invitation or message, I'll reply within 4 hours with a clear breakdown of how I'd approach your specific problem.

🤝 A little more about me:
I help startup founders and SaaS teams ship full-stack web applications that don't break when real users show up. Next.js frontends, NestJS backends, GraphQL and REST APIs, real-time WebSocket features, RAG-powered AI, and Stripe billing from day one.

If your backend and frontend don't quite talk to each other the way they should, or your app works in staging and falls apart in production, that's exactly the gap I close.
