About Koushik Nagaraj

I\'m an AI Safety and Generative AI expert at Google with 9+ years building systems that detect, prevent, and mitigate misuse of large language models (LLMs) and ad abuse at scale.Currently, I lead development of AI safety classifiers, autoraters, and robust misuse-prevention frameworks for LLMs at Google. In addition, I like to use AI to drive business outcomes on productivity and cost reductions.Previously, I architected large-scale threat detection systems for DigiKavach and AdSpam, identifying 50+ fraud patterns and enabling ~$XX0M ARR protection.My foundation in data analytics and ops was built at Paytm, where I led Catalog Analytics, drove Staetgic initiatives and Automations. During my 3.5 years there, I built scalable ML based proof of concepts, reporting and analytics solutions using Python, Hive, SQL, and Salesforce — including increasing Catalog NPS from -2% to 60% in just 6 months.My expertise includes:AI Safety & Misuse PreventionLLM Fine-tuning & Prompt EngineeringDNN Classifier DevelopmentGenAI Solution DesignThreat Detection at ScaleRisk & Predictive Analytics
