Top SchoolSean Dempsey is a seasoned software leader based in Austin with over 14 years of professional experience and a 20+-year background in hands-on development across security, observability, and mobile platforms. Currently a Staff Lead on Duo Security’s Data Science and Engineering team, he designs zero-trust policy backends and public APIs while blending SSO and security-first thinking into production services. He previously led large-scale observability and SRE efforts—owning architecture, tracing, centralized logging, and incident analysis—at scale using AWS, Python, Elasticsearch, Kubernetes, and distributed tracing. As a founder he built native iOS apps in Objective C++ and OpenGL ES, and in past roles has driven 100x throughput improvements in document indexing systems and built high-throughput Scala/Java services for large web platforms. Comfortable moving between architecture and code, he pairs product ownership with deep operational experience and a track record of shipping resilient, measurable systems. Colleagues rely on him for pragmatic solutions that bridge security, observability, and scalable data engineering.
