Dave Fisher, Apache Software Foundation Member, Apache POI PMC, Apache OpenOffice PMC, Apache Incubator PMC, Apache Flex PMC/Mentor, Apache Olingo Mentor. Spoke at Apachecon NA 2010 and 2011 on Apache POI. Throughout my career I have worked on various aspects of document creation and transformation in high volume on demand mass customization workflows. We were attracted to Apache projects for all aspects: a favorable license, open code base, contribution of features, and a community of like minded developers.
