Tobi is currently leading the effort to support Project Valhalla features on Openj9. This project proposes complex and far reaching changes to the JVM as it touches all the major components (runtime, JIT, GC, class libraries, tooling). Tobi frequently collaborates with other OpenJ9 committers to ensure that the design of these new features are compatible with how OpenJ9 works and to also make sure that these features will perform well on OpenJ9. Tobi lead's the effort on the ValueTypes prototype on OpenJ9. These responsibilities include designing, writing and reviewing code as well as working with other committers to balance performance and future maintainability in the implementation.
Tobi has also been very involved in the Openj9 community. He frequently attends the weekly community calls and has given lightning talks   on Project Valhalla at the weekly meetings. He is also involved in the broader Java community and has given talks on OpenJ9  and related features   at various conferences.
Tobi has been very active on the Eclipse OpenJ9 project and has contributed 93 commits (17,693 ++ 5,453 --) . He also frequently mentors first time committers through code reviews (100+). He has used his experience as a runtime developer to provide valuable feedback in various PRs and issues.
