I am an allround BI professional with more than 15 years of experience in extracting valuable information from raw business data. As a keen learner I have come accross multiple BI platforms, always looking for more advanced tools and embracing new technologies. The last 3 years I have dedicated to Hadoop and its ecosystem. I lecture and write about its promise, especially for the BI world. With my roots in BI I have developed into a technical IT generalist with a strong point in translating complex issues into tangible business implications and comprehensible terminology. I advocate open source to be able to tweak the tools I like into doing exactly what my customers want.
