I design agentic AI systems for pharma R&D and lead the teams that take them to production.
I am an AI engineer with almost five years of experience taking models from research to production across LLM agents, NLP and computer vision. At ZS Associates I design agentic AI for pharma R&D and lead development of a production suite of agentic document tools for a global pharmaceutical sponsor. I also research low-resource Bangla NLP, with papers at NAACL 2025 and EMNLP 2023.
