Full-Stack & AI Engineer

I build AI-powered web apps that actually ship.

From idea to production — React + FastAPI front-to-back, grounded LLM/RAG systems, and clean AWS deployments. Fast, reliable, and a little bit fun.

What I can build for you

End-to-end product engineering, not just snippets.

Full-Stack Web Apps

React / Vite front-ends and FastAPI / Node back-ends, wired together end-to-end with auth, APIs, and real databases.

  • Responsive, accessible UIs
  • REST & streaming APIs
  • Auth & user management

AI & RAG Systems

Grounded LLM apps that cite their sources and refuse to hallucinate — retrieval, guardrails, OCR, and streaming answers.

  • Document Q&A & chatbots
  • Hybrid vector + keyword search
  • Groundedness & cost controls

Cloud & Deployment

Ship to AWS with a real domain, HTTPS, sane security, and cost guardrails baked in — not a localhost demo.

  • EC2 · Route 53 · Cognito
  • HTTPS & CI-friendly setup
  • Spend & abuse controls

Featured work

Real, deployed products — go click around.

Live

Conversational AI Agent

A natural-language agent that answers questions over structured data through a clean FastAPI service — deployed alongside Veridoc on the same AWS box behind HTTPS.

Hi, I'm Gagandeep 👋

I'm a full-stack engineer who loves turning fuzzy ideas into polished, production apps. I'm most at home where web meets AI — building grounded LLM systems that people can actually trust, with the front-end, back-end, and cloud all wired up properly.

I care about shipping: clear UX, honest behavior, and infrastructure that won't surprise you on the bill.
