Available for freelance projects Full-Stack & AI Engineer

I build AI-powered web apps that actually ship.

I help founders & teams turn ideas into live, production AI products — React + FastAPI, grounded LLM/RAG, deployed on AWS. Usually in weeks, not months.

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.

Veridoc — Document Q&A you can trust

Problem: teams lose hours digging through PDFs, and most AI chatbots confidently make things up.
What I built: upload your documents, ask in plain English, and get answers with clickable source citations — plus an honest “I don’t know” instead of a hallucination. Hybrid search, a groundedness guardrail, scanned-PDF OCR, per-user logins, and a spend circuit-breaker.
Result: answers you can actually act on — live on AWS.

AI Lead Engine — your automated SDR

Problem: leads pile up and go cold while you qualify them by hand.
What I built: an automation that enriches each lead from the web, scores it with AI, logs it to a Google Sheet CRM (no duplicates), emails you the hot ones with a ready-to-send reply, and self-heals with error alerts.
Result: every lead handled in seconds, 24/7. Submit a sample lead on the demo and watch it run.

Why clients work with me

Proof over promises — everything here is real and running.

Live, not slides

Every project above is deployed and clickable. You can try the real thing before we ever get on a call.

I ship to production

Real domains, HTTPS, auth, and databases — not a localhost screenshot. I take projects all the way to live.

Honest & cost-aware

Grounded AI that won’t hallucinate, and infra with spend guardrails — so the result is trustworthy and the bill never surprises you.

How I work

Small loop, fast feedback, shipped at the end.

Understand

Pin down the real problem and the simplest thing that solves it.

Design

Clear data model, clean API contract, and a UI that feels good.

Build

Ship end-to-end in tight iterations — verified as it goes.

Deploy

Live on real infra with HTTPS, auth, and cost controls.

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.

Ways to work together

Pick what fits — and if you’re not sure, just ask.

Fixed-scope project

A defined build — an app, an AI feature, or an automation — with a clear deliverable, timeline, and price agreed up front.

Best for a specific outcome
One quote, no surprises

Hourly / iterative

We build in tight loops when scope is still evolving — you see progress at every step and steer as we go.

Best for discovery & MVPs
Flexible & transparent

Ongoing support

A monthly retainer for new features, improvements, and keeping things running smoothly after launch.

Best for live products
Priority response

Quick questions

How do we get started?

Email me a few lines about your project. I’ll reply within a day with questions, a suggested approach, and a rough estimate — no obligation.

Where are you based / what timezone?

I’m based in India (IST) and work with clients worldwide. I keep flexible hours and overlap with most timezones for calls.

Who owns the code?

You do. On completion, all code and assets are yours — in your repositories and accounts.

Can you take something from idea all the way to live?

Yes — that’s the whole point. I design, build, and deploy to real infrastructure with HTTPS, auth, and cost controls. Every project above is an example.

What’s your stack?

React/Vite, FastAPI/Node, Python, RAG/LLMs, vector DBs, n8n automations, and AWS (EC2, Route 53, Cognito). I pick the simplest tool that fits the job.

Have a project in mind?

Tell me what you're building. I reply within a day and love a good problem.
