Top SchoolPatrick Niemeyer is a veteran software engineer and author best known for O'Reilly's Learning Java series, a globally adopted textbook available in nine languages and winner of a 2001 Reader's Choice award. With 13+ years of professional experience and a background that spans senior architecture roles at financial institutions to startup CTO and co-founder positions, he blends deep Java expertise with practical product-building. He contributed to widely used developer tooling as the creator of the BeanShell Java scripting language and moves fluidly between systems-level architecture and hands-on app development. Recent work focuses on ML and Web3—implementing neural-style generative models, building decentralized VPN/bandwidth markets on Ethereum, and contributing UI and localization to the WHO COVID-19 Flutter app. Based in Missouri, he pairs academic-friendly teaching experience with production-grade engineering, regularly shipping cross-platform mobile, backend, and crypto-native systems. Colleagues can expect a pragmatic engineer who still writes educational code and tooling that endures.
