Rockstar🎓
Top SchoolHenry Sudhof is a senior software engineer and tech lead specializing in source interoperability and core build/release infrastructure, currently leading a team at Google focused on bridging internal and external development ecosystems with emphasis on AI support and supply chain security. With a PhD in formal methods and nine years at Google, he pairs deep theoretical expertise in type systems and security with hands-on systems work in C++ and Java for high-risk, large-scale platforms like payments and search.
