He has a lot of experience in a wide range of technologies, ranging from backend technologies, such as Java and Scala, to frontend development using HTML5, CSS, and JavaScript. Besides working with these technologies, Jos also regularly speaks at conferences and likes to write about new and interesting technologies on his blog. He also likes to experiment with new technologies and see how they can be best used to create beautiful data visualizations, the results of which you can see on his blog at http://www.smartjava.org/. Jos is currently working as a consultant for a large Dutch financial institution and has just finished a function as an enterprise architect for Malmberg, a large Dutch publisher of educational material. There, he helped to create a new digital platform for the creation and publishing of educational content for primary, secondary, and vocational education. Previously, Jos worked in many different roles in the private and public sectors, ranging from private companies, such as Philips and ASML, to organizations in the public sector, such as the Department of Defense.
