David Simms

Java Platrform Group - Oracle

Hands on Java Virtual Machine engineering for over 25 years, first with the JRockit VM and then Hotspot JVM. Involved in Project Valhalla over 10 years now, I might have filed an almost 3000 commit PR to integrate the first really big step in getting Valhalla into OpenJDK. On the side I manage Oracle's Java Platform Group engineering site in Stockholm Sweden.
