I build production-ready GenAI systems, RAG pipelines, and autonomous AI workflows.
IndiaWhat I'm looking for
I've built end-to-end GenAI applications including an Advanced RAG Document Intelligence platform that lets users chat with PDFs and Markdown using local and cloud LLMs. I designed its LangChain pipeline, ChromaDB vector storage, Streamlit interface, source citations, and persistent architecture to improve reliability and reduce reprocessing overhead.
During my AWS internship at Cognizant, I developed a Credit Management System with Lambda, S3, DynamoDB, AWS Glue, and PySpark ETL workflows. I've also built stateful LangGraph agents with tool calling and memory persistence, and an AI-assisted portable ECG analyzer that achieved 94.2% classification accuracy with sub-2-second latency.
