Top SchoolEthan Cowan is a privacy-minded founding technologist and consultant with 11 years of experience building and deploying ML and backend systems across startups, academia, and industry. He blends hands-on engineering (Django, PostgreSQL, TensorFlow/PyTorch, cloud on AWS/GCP/DigitalOcean) with strategic leadership—helping early-stage teams make critical technology decisions and leading projects from research to production. At Harvard he developed secure platforms for differential privacy research and later co-authored the O’Reilly textbook Hands-on Differential Privacy, reflecting a rare combination of practical ML skills and formal privacy expertise. He specializes in architecting RAG systems and complex language models while insisting on ethical guardrails that don’t slow delivery. Based in Baltimore, he runs a consulting practice and a “done-for-you” online presence startup, and is available for advisory calls and development engagements. A PhD student in History and Philosophy of Science and Technology with advanced degrees in theology and software engineering, he brings interdisciplinary perspective to technical risk and product strategy.
