Hemang Patel
AI Full-Stack & GenAI Engineer
I build production full-stack applications and LLM-powered systems — from React & Next.js frontends to FastAPI/Node backends, RAG pipelines, and AI observability. 3+ years of experience, based in Toronto.

Engineer across the full stack — with an AI core
I'm a full-stack developer with 3+ years of experience building scalable backend systems, APIs, and AI-powered products. I started out as a Computer Engineer in India, spent two and a half years at Techmicra shipping enterprise web apps, then moved to Canada to deepen my craft — and these days a lot of that craft lives in the AI layer: RAG pipelines, LLM observability, and OpenAI APIs wired into real products.
Most recently I was a full-stack co-op at PopIn here in Ontario, and I finished an Ontario Graduate Certificate in IT Solutions at Humber College with a 3.9 GPA. I care about systems that hold up in production — clean APIs, fast queries, and tooling that makes failures easy to find. This site is part of that: the 3D desk and the terminal below are things I actually built, not screenshots.
The stack I build with
Proficiency across the GenAI, frontend, backend, and cloud layers — the same tools that power the projects below.
Selected work
Grouped by domain. AI & ML projects are highlighted — each links to its GitHub repository.
AI Failure Investigation System
An LLM observability platform that tracks, analyzes, and diagnoses AI response failures in production — monitoring prompt versions, retrieval quality, hallucination risk, and response confidence.
Enterprise Knowledge Retrieval (RAG)
A Retrieval-Augmented Generation platform for contextual Q&A across business documents using semantic search, vector databases, and LLM-powered response generation.
LSTM Time-Series Forecasting
Time-series forecasting with LSTM neural networks implemented in PyTorch — data prep, model training, and evaluation in a reproducible notebook.
FitFeast
AI-powered meal planning & health tracking platform with modular backend APIs, real-time external data integration, and AI-driven personalization.
Real-Estate (MERN)
Full real-estate listing platform built on the MERN stack with server-rendered views.
Stream-AI
A Netflix-style streaming clone modeled on the real tech stack and UX patterns Netflix uses.
