I've built production LLM agents and data products at Rapido, Snowball AI, and Trissino AI, turning business questions, taxability research, and competitive intelligence into automated workflows.

At Rapido, I developed a Text-to-SQL generator for product managers and analyzed Bargain rollout funnels across 300+ cities, contributing to a 10% average improvement in key engagement metrics.

At Snowball AI, I built an autonomous product-taxability research agent across 50 US states at 94% accuracy, eliminating 40+ hours of manual research each month. I also created evaluation frameworks using BERTopic and HDBSCAN to uncover sales objections linked to a 35% improvement in deal velocity.

I've also shipped RAG and edge-AI systems, including a SaaS PDF intelligence product serving 150+ users and an intrusion detection system achieving 92% precision. I'm completing a B.Tech in Computer Science and Engineering at IIIT Kottayam and have led teams as a Smart India Hackathon national winner and Drama Club President.
