🚀 Featured Projects

🏥 AI Medical Chatbot — Production RAG System

Answers medical questions grounded in verified clinical documents using retrieval-augmented generation

  • RAG pipeline — PDF ingestion → chunking → Pinecone vector search → Gemini LLM generation
  • Deployed on AWS EC2 with full CI/CD via GitHub Actions → Amazon ECR → self-hosted runner
  • Stack: LangChain · Pinecone · Google Gemini · FastAPI · Docker · AWS EC2/ECR

✍️ AI Blog Generator — Agentic LangGraph Pipeline · Live Demo →

Generates high-quality blog posts using a multi-node agentic graph with self-evaluation and revision loops

  • LangGraph agentic graph — title → outline → content → quality check → auto-revision loop
  • Conditional routing — multilingual translation (Hindi, Marathi, French) via graph edges
  • Tone control — professional / casual / academic / humorous writing styles
  • Streaming API — real-time node-by-node progress via FastAPI StreamingResponse
  • Stack: LangGraph · Groq LLaMA 3.1 · FastAPI · Streamlit · Render · LangSmith

💡 What I Build

I focus on the gap between AI research and production systems — taking LLM capabilities and deploying them as reliable, observable, maintainable services:

  • RAG systems that retrieve grounded context instead of hallucinating
  • Agentic pipelines using LangGraph that loop, evaluate, and self-correct
  • REST APIs with proper schemas, error handling, and streaming
  • CI/CD pipelines that build, push to ECR, and deploy to EC2 automatically
