At eBay, I architected and led an enterprise RAG-based AI Assistant for complex authentication workflows, using hybrid retrieval, reranking, and automated evaluation. I also designed GenAI pipelines that integrated GPT models into enterprise workflows, including a handbag authentication solution that achieved ~90% F1.
I led the lifecycle of sneaker authentication models, from data pipelines and training through deployment, monitoring, drift detection, and automated monthly retraining; they achieved ~91% balanced accuracy. I also designed and delivered eBay's CE Document Management platform for EU/UK regulatory compliance, eliminating a third-party dependency.
Earlier at eBay, I built backend, search, and event-driven platforms for trust and prohibited-content systems, including applications processing 10M+ events daily. At GE HealthCare, I built benchmarking and automated testing frameworks, and in earlier roles I developed Java services, APIs, and deployment automation.
