At Egencia, American Express Global Business Travel, I lead a portfolio spanning AI, payments, fraud prevention, identity, compliance, enterprise administration, and workflow automation. I own strategy from customer discovery through launch, adoption, and scale.

I designed and built an AI compliance assistant using RAG, semantic search, Supabase vector databases, and LLMs to retrieve and explain policies with auditable outputs and human oversight. I also led AI-assisted payment reconciliation and configuration workflows that combine LLM reasoning with deterministic business rules.

My products have reduced sanctions-screening false positives by 90%, onboarding time by 60%, operational costs by 80%, and payment configuration effort by 30%. I integrated virtual-card capabilities that brought manual reconciliation effort close to zero and fraud-screening APIs that prevented approximately $25K per month in losses.

Previously at Oracle, I led Digital Experience for Communications and Application Composer, delivering configurable product, pricing, low-code, workflow, and API capabilities that helped customers launch products 80–90% faster and build enterprise applications 4–8x faster. I bring an engineering foundation in distributed systems, APIs, data flows, and enterprise software, and I build AI systems that amplify human judgment rather than replace it.
