Dustin Kut Moy Cheung was born and raised in the island of Mauritius. His interest in computers was sparked when he got his first computer at the age of nine. He went on to study Electrical Engineering at McGill University in Montreal, Canada. Dustin is currently working as a productization engineer in the JBoss productization team at Red Hat.

Bartosz Majsak works as a software developer at Cambridge Technology Partners, based in Zurich. He is passionate about open source technologies and testing methodologies. He is a proud JBoss Community Recognition award recipient for 2012 and 2013. He's also an Arquillian team member and the lead for two modules: Persistence Extension (makes writing database-oriented tests easier) and Spock Test Runner (gives your Arquillian tests some BDD and Groovy love). One thing that perhaps proves Bartosz is not a total geek is his addiction to alpine skiing.

Jakub Marchwicki has been in the software development industry for the past 10 years—wearing multiple hats, getting his hands dirty in multiple environments, and securing both technical as well as the business side of The Thing, which is an engineer with a human-friendly interface. Additionally, he has worked with a variety of languages and frameworks.

Jakub has always considered programming a tool to solve real-life problems in a pragmatic way. He has always stayed close to the business side of the solution, focusing on the technology. He combines his daily job of managing a horde of software engineers at Young Digital Planet with lectures, technical trainings, and commitment to Gdańsk Java User Group.
