Who I Am

I'm a Python developer and AI engineer based in Tirupati, Andhra Pradesh with 4+ years of experience across automation, infrastructure monitoring, machine learning, and cloud systems.

Right now I'm deep into Generative AI — building RAG pipelines, working with LLMs, and exploring how to make AI systems that are grounded, reliable, and actually useful in production. My stack includes LangChain, ChromaDB, FastAPI, Streamlit, and Groq.

Open to opportunities in Gen AI Engineering, Python Development, and Machine Learning roles where I can build systems that matter.

What I've Built

PROJECT_01
DocMind — RAG Chatbot

Full-stack document Q&A chatbot built from scratch. Upload a PDF, Word, CSV or TXT file and ask questions — answers are grounded strictly in the document using a complete RAG pipeline with conversation memory and MMR retrieval.
