Michael Hunger has been passionate about software development for more than 30 years.
For the last 12 years, he has been working on the open source Neo4j graph database filling many roles, most recently leading product innovation and developer relations. As caretaker general of the Neo4j community and ecosystem he especially loves to work with graph-related projects, users, and contributors.
As a developer, Michael enjoys many aspects of programming languages, learning new things every day, participating in exciting and ambitious open source projects, and contributing and writing software-related books and articles. Michael has spoken at numerous conferences and helped organize several of them. His efforts got him accepted to the JavaChampions program.
Michael helps kids to learn to program by running weekly girls-only coding classes at local schools.
