I work on fraud detection and risk ML systems at Stripe, building transformer-based models and GPT-4 powered agentic tools that help protect payments at a global scale. My work spans the full ML lifecycle, from fine-tuning LLMs on proprietary transaction data to deploying low-latency inference services that process billions of transactions daily.

At Razorpay, I built end-to-end fraud detection pipelines and real-time ML inference services handling 1,000+ requests per second across India's payments ecosystem. I also partnered closely with compliance teams on model explainability and AI governance to meet RBI regulatory standards.
