Xavier G is a Staff Engineer with 14 years of experience specializing in Android and TV platforms, currently driving Datadog’s Mobile and TV SDKs across Android, Android TV, Fire TV and Roku. He has deep roots in the Android ecosystem since 2009, authored SDKs for Datadog and Deezer, and maintains numerous open-source Android projects—including contributions to well-known apps like AntennaPod. A former teacher and frequent conference speaker, he excels at translating complex technical concepts into clear guidance and mentoring across distributed feature teams. Technically fluent in Kotlin, Java and Brightscript (and familiar with Python, JavaScript and C/C++), he navigates Android Framework, NDK and CI tooling with ease and has practiced TDD since 2014. Beyond product work he builds developer-facing tools, untangles complex git histories, and still finds time to ship open-source libraries like Elmyr. Based in Nogent-le-Rotrou, France, he combines hands-on engineering with community engagement and a persistent curiosity.
