What I'm looking for

I'm looking to build AI/LLM-powered systems, especially RAG applications and production-oriented microservices, while growing my hands-on experience in machine learning, NLP, retrieval, and LLM inference.

I'm an IIT Guwahati Data Science & AI undergraduate and LLM Intern at KPMG India, contributing to production-oriented RAG microservices for document processing, retrieval, reranking, and LLM inference.

I develop and test FastAPI REST APIs for document ingestion, embedding generation, retrieval, and knowledge-base management using LangChain, LangGraph, Sentence Transformers, ChromaDB, and LLM APIs.

I've built a medical RAG chatbot using LangChain, FAISS, LLaMA 3.1, and Hugging Face Sentence Transformers to provide context-grounded medical Q&A and reduce hallucinations. I also built and deployed a healthcare premium prediction application with XGBoost models achieving R² of approximately 0.98.

My work also includes a TensorFlow CNN that classified 7,000+ MRI images across four tumor categories with 96% validation accuracy. I bring foundations in machine learning, deep learning, NLP, Python, SQL, and hands-on AI engineering.
