Hi, I'm Affan Shah

AI Application Engineer | Computer Engineering Student

I design and build AI-powered applications, agentic systems, and RAG pipelines with a focus on turning LLM capabilities into reliable, deployable software.

My work spans agent orchestration, retrieval pipelines, backend systems, APIs, and full-stack applications — from experimentation and evaluation to deployment.

What I Build

  • Agentic AI Systems — multi-step workflows, tool-using agents, autonomous task execution, and stateful AI applications
  • RAG Systems — document ingestion, preprocessing, embeddings, retrieval, context construction, and grounded generation
  • AI Applications — LLM-powered products built around practical user workflows rather than simple chat interfaces
  • Backend Systems — Python, FastAPI, databases, APIs, authentication, and service architecture
  • Full-Stack Applications — Next.js, TypeScript, and modern web applications for deploying AI systems

Engineering Stack

AI / ML: LangGraph, LangChain, RAG, LLMs, NLP, TensorFlow Backend: Python, FastAPI, REST APIs, PostgreSQL, MongoDB Frontend: Next.js, TypeScript, React, Tailwind CSS Tools & Infrastructure: Git, GitHub, Docker, Vercel, Render

I learn by building real systems, debugging what breaks, and shipping what works.
