Full-Stack Engineer for Fast-Moving AI Teams | Backend & RAG/LLM

Job Success
Lahore, Pakistan - 4:58 pm local time
I work with teams moving fast on AI — shipping features, MVPs, and products faster than most — and make sure what gets built holds up past the demo: backend systems that can't afford to fail (HIPAA-conscious healthcare platforms, payment flows that have to reconcile perfectly), and AI/RAG pipelines that survive real traffic, not just a screen-share.
Most freelancers can describe this work. I've shipped it — live, in production, for clients who couldn't afford it to go wrong.
What makes me different
→ I don't bolt on an API call and call it "AI integration." I design retrieval, structure outputs, and handle the failure modes that only show up under real traffic.
→ I've built this inside systems where mistakes were expensive: multi-tenant SaaS, payment processing, HIPAA-conscious healthcare infrastructure.
→ I own the system, not just the ticket — I find where things break and fix them cleanly, not just where I'm told to look.

What I'm best at
⚡ AI-speed builds, made production-ready
Reviewing, hardening, and scaling apps built fast with AI tooling — so the backend doesn't buckle the moment real users show up.
đź’ RAG & LLM systems
Retrieval pipelines, structured LLM outputs, and AI workflows built to survive production traffic — not prompt wrappers stitched onto an API.
đź’ Backend for regulated & high-stakes SaaS
Django, FastAPI, PostgreSQL — multi-tenant architecture, audit-minded design, RBAC, private AWS VPC networking.
đź’ Payments & integrations
Processor flows, webhooks, reconciliation, and reporting across account types — the parts of the system that can't be allowed to silently fail.
đź’ Cloud delivery
AWS, Docker, CI/CD — deployed, monitored, and maintained, not just spun up once and handed off.
Proof
▪ Multi-tenant locker SaaS — FastAPI + React, real-time device signaling across mobile/kiosk clients, integrated payment processing
▪ AI threat-intelligence platform — retrieval-driven analysis with structured, automated reporting in place of manual review
▪ HIPAA-conscious healthcare platform — private AWS VPC, RBAC, audit-minded design for regulated referral data
If you're moving fast with AI and need the backend to hold up under real usage — or a system built by someone who's already broken these in the ways that matter — message me with the stack and the problem.
