About

I'm an AI Research Associate working at the intersection of NLP, Generative AI, and public health. With hands-on experience in Large Language Models (LLMs), Retrieval-Augmented Generation (RAG), and LangChain, I build intelligent systems that simplify real-world problems especially in mental health and finance. From research on AI-powered telehealth solutions (TeleMANAS) to working with financial insights using NLP pipelines, I bring both technical depth and domain awareness. I specialize in building end-to-end AI workflows using PyTorch, Hugging Face, and modern data engineering practices. I’m deeply motivated by using AI to drive social impact, improve mental health access, and enable financial literacy through smarter systems. If you're working on projects in NLP, LLMs, healthcare AI, or applied research, I’d love to connect and collaborate.
