Next.js & Supabase Expert | Multi-Tenant SaaS, RLS & AI Code Audits

Dhaka, Bangladesh - 1:55 pm local time
I'm a full-stack engineer with 7+ years of experience building and hardening production SaaS platforms on Next.js and Supabase. Increasingly, that means taking over codebases that started as an AI-assisted build (Cursor, Claude Code, Lovable, v0, low-code) and turning them into something secure, coherent, and ready for real customers. If your app "mostly works" but you're not confident the Row-Level Security is airtight, tenant data is properly isolated, or the AI-generated logic will hold up in production, that's exactly where I add the most value.

What I do:

Audit and stabilize existing Next.js/Supabase codebases: identify what to keep, refactor, or rebuild, and where frontend workflows have drifted from backend/RLS logic
Design and verify multi-tenant architecture: RLS policies, org_id isolation, role-based access, and written tenant-isolation tests that prove data can't leak across tenants
Build production-ready SaaS from scratch when that's the better path: Supabase Auth (email, OAuth, magic link), Realtime, Edge Functions, PostgreSQL schema design
Integrate AI features responsibly: RAG with pgvector, GPT, Claude, Gemini, hybrid search, agentic workflows, without letting AI-written code become the weak point

At Toptal, I ran A/B tests that helped a client grow monthly leads from 2,500 to 4,500. On another project, I helped migrate a legacy system with 50M+ records to AWS and cut page load times from about 60 seconds to under 500ms. Before all of that, I came up through competitive programming (1866 Codeforces rating, 1500+ problems solved, top 11 in an inter-university contest), which is where the habit of finding the actual bug instead of the obvious one comes from.

Core stack: Next.js, TypeScript, Supabase, Prisma, PostgreSQL, AWS (Elastic Beanstalk, RDS, S3, CloudFront, Lambda), Stripe, Vercel

I read code I didn't write for a living at this point, and I'll tell you honestly if something isn't worth building rather than just implementing it. If you need someone to review, secure, or finish an existing Supabase project, or build one properly from day one, feel free to invite me.
