He was recognised by his peers as a Java Champion in 2012 for his services to the Java community.

As a leading expert on technical team optimisation, his talks and presentations are in high demand by major conferences (JavaOne, Devoxx, OSCON, FOSDEM, QCon, etc). Often you'll find him challenging the industry status quo in his alter ego "The Diabolical Developer".
Presentation: TweetGarbage Collection - The Useful Parts
This presentation will give the busy Java/JVM developer an overview of how Garbage Collection (GC) works in the JVM and the common collectors that are used. I'll also cover how to read and interpret the scary GC log format and most importantly, offer strategies to deal with badly behaving memory characteristics such as Premature Promotion, high pause times and of course the dreaded OutOfMemoryError (OOME!).
Who Should Attend: Any Java/JVM developer or ops person who wants to learn about the deep dark secrets of the JVM's GC sub system.
Presentation: TweetNoHR Hiring
Hiring the right technical people is critical to the success of your business and it's a very difficult thing to get right. The consequences of hiring the wrong person range from the destruction of team morale, failure of business and IT projects. Not to mention the wasted time that you will have to spend demonstrating and documenting that they were incompetent enough to be fired. The good news today is that finding the right person is easier than it ever has been before because of the increasing number of social coding and technical communities. In this talk we will explain how to make the best use of community resources to find your ideal employee as well as sharing some horror stories.
