Rawalpindi, Pakistan - 1:48 pm local time
Need a production backend with real auth, roles, and multi-tenant data isolation, not just a CRUD API? I build and harden FastAPI + Next.js systems for teams past the prototype stage: authentication (JWT/OAuth/MFA), role-based access control, per-tenant data boundaries, rate limiting, and audit logging that holds up to a client or compliance review.

I also build the AI layer when a product actually needs it, RAG/chat with cited answers, not a bolted-on widget.

Recent: $2.5k FastAPI + React MVP delivered end-to-end (5.0 rating).

What you get in Phase 1 (~1 week):
▪ Scoped working milestone: core API, database schema, auth + role/tenant model, admin shell
▪ Fixed-price milestone before full build, no open-ended hourly drift
▪ Clean handover: docs, repo structure, deployment + environment notes

Stack: Python (FastAPI), Next.js/React, PostgreSQL, Redis, Docker, AWS; OAuth/JWT, RBAC, multi-tenant architecture; OpenAI/Claude, LangChain, pgvector/Pinecone when RAG is in scope.

How I work: quick scope call or async brief, Phase 1 milestone in ~1 week, iterate, production-ready handover with docs.

Share your repo, spec, or current architecture and what you need secured or built, I'll reply with a clear plan and a fixed-price Phase 1 offer.
