At Echo INC, Iām learning and building with large language models, retrieval-augmented generation, and AI agents. I also completed a Clinical Informatics Internship at 57375 Hospital, where I observed how data-driven approaches support patient care.
I fine-tuned TinyLlama-1.1B for news summarization using LoRA/PEFT and 4-bit quantization, improving ROUGE-1 by 72% over the zero-shot baseline while training less than 1% of the parameters. I also built DocuMind-RAG, a question-answering system for research papers that combines hybrid search and reranking with a FastAPI backend and Streamlit interface.
