At Intuit, I build generative AI experiences for Intuit Assist across TurboTax and QuickBooks, serving products used by approximately 100 million customers. My RAG pipelines, custom financial LLMs, model routing, and safety guardrails helped deflect 40% of support contacts and improve task completion by 25%.

I build reliable AI systems end to end: evaluation harnesses, retrieval grounding, responsible-AI guardrails, real-time feature platforms, and high-throughput inference. My work has reduced hallucinations by 35%, raised answer accuracy to 92%, and sustained sub-100ms p99 performance across 730M+ annual AI-driven interactions.

Previously at Paytm, I built transaction intelligence, fraud-risk, and income-verification models processing more than 150M transaction records daily. I improved merchant and category classification accuracy by 18% and reduced false-positive risk decisions by 24%.

I enjoy turning difficult financial-domain problems into production ML and GenAI products using Python, AWS, distributed streaming systems, and rigorous evaluation.
