What started as a single developer's passion project now powers mission-critical APIs for tech giants like Twitter/X, Netflix, Amazon, AirBnB, and Atlassian. As the engine behind Spring for GraphQL and with over 2.2 million monthly downloads, GraphQL Java has become the Java implementation of GraphQL.
How does a volunteer-driven open source project not just survive, but thrive for a decade? In this talk, we'll share the crucial technical decisions and community building strategies that transformed a hobby project into an industry standard. We'll share how we fostered contributions from over 250 volunteers while maintaining high code quality and project momentum. You'll walk away with actionable insights to help you lead any software project, whether it's open source or enterprise.
About the speakers: we are the maintainers of GraphQL Java, who have guided the project from its first commit to becoming the industry standard.
I'm a maintainer of GraphQL Java and software engineer at Atlassian. I've published a book, GraphQL with Java and Spring, all about the official Spring for GraphQL integration and the GraphQL Java library.
