Summary
🤩
RockstarMichael Hunger is a seasoned product and innovation leader with 19 years of experience, currently serving as Sr. Director of Developer Relations & User Innovation at Neo4j from Dresden. A longtime graph technology pioneer and Java Champion, he combines hands-on engineering—contributions to high-profile projects like Neo4j’s graph algorithms, APOC procedures, spatial library and batch importer—with strategic developer advocacy and community stewardship. He champions open source, mentors developers (including teaching girls to code), and has driven integrations across ecosystems from Spring Data to LangChain and vectorized retrieval with Neo4j. Equally comfortable refactoring core libraries and orchestrating docs/DevOps pipelines, he brings a rare blend of deep backend/database engineering and program-level leadership. His editorial and conference roles (InfoQ, O’Reilly reviewer, GOTO program chair) underline a talent for translating technical depth into clear narratives and community impact.
