About

I lead engineering teams that turn cutting-edge technology into robust, scalable products. At Meta/WhatsApp, I built and scaled multiple zero-to-one products across payments, business platforms, and most recently, generative AI. I’ve launched secure real-time payment systems, scaled global developer-facing APIs, and led the integration of WhatsApp into Meta’s business suite — a project projected to drive $500M+ in revenue. Today, I lead generative AI integration at WhatsApp, shaping product architecture and user experience in close partnership with MetaAI. My background spans backend systems (Erlang, Kafka, Clojure), cross-functional execution, and product strategy under high regulatory and privacy constraints. I’m especially passionate about building at the intersection of infrastructure, user experience, and responsible AI — where ambiguity is high and the stakes are real.
