As a Product Manager in the Modern Application Platform Business Unit at VMware, Leon’s focus is to help developers accelerate their Kubernetes journey, leveraging open source tools, and help drive healthy and safe communities. He is very passionate and outspoken when it comes to the needs of developers because he believes developers can (help) transform their business by getting the right pieces of information to the right people at the right time in the right context.

Leon is crazy about serverless and container technologies, he enjoys writing code, speaking at conferences and meetups, and blogging about it. Before joining VMware, Leon was a Developer Advocate at JFrog and TIBCO where he helped developers get the most out of their dev tools and worked on the open source project Flogo. Leon holds a B.S. in Computer Science from the University of Applied Sciences in Rotterdam.

In his personal life, he’s on a mission to taste cheesecake in every city he visits (suggestions are welcome @retgits). As much as he loves to share his thoughts, opinions and source code with you, he will not share his cheesecake…
