Andy Le is an engineering leader and builder with 12+ years of experience designing large-scale distributed systems, payment ledgers and social listening platforms from Vietnam. He began his career in security—authoring early research that flagged the first reported Google Chrome vulnerability—and has since led teams at ZaloPay, NAB and FPT Pay to deliver high-throughput, production-grade services (aiming for 30k TPS in payments). A practical polyglot who has shipped crawlers, stream analytics, ML pipelines and backend services, he also contributes to notable open-source projects like mqtt.js, Apache Avro and Redis. Andy champions open engineering culture—founding ZaloPay’s open-source program, an engineering blog and the Vietnam Data Scientists community—and builds internal training programs to grow junior engineers. Now shifting toward product-minded leadership, he blends deep systems expertise with a curiosity for entrepreneurship, history and hands-on problem solving.
