We’re thrilled to welcome Dirkjan Bussink to the GitHub Systems team.

He’ll be working on GitHub performance β€” building tools that bring visibility to slowness, speeding up everything from Ruby to MySQL, and eliminating inefficiencies wherever he finds them.

You might have seen Dirkjan’s work on Rubinius, where he’s the #2 contributor of all time. We’ll be sure to put his impressive knowledge β€” ranging from high-level Rails code to low-level concurrency problemsΒ β€” to good use.

Dirkjan joins us from Enschede in the Netherlands. You can follow him on GitHub and Twitter as @dbussink.
