About

As a Computer Science graduate student at Columbia, I’m passionate about the intersection of AI Agents, NLP and systems. I’ve built scalable, intelligent and secure systems that leverage agentic reasoning, LangChain with dynamic chain-of-thought reasoning, retrieval-augmented generation (RAG), and large language models to automate complex workflows. More recently, my focus has shifted toward making AI agents handle complex data more effectively—making them smarter, more adaptive, and accessible to everyone.
