Matt Casters has been an independent senior BI consultant for almost two decades. In that period he led, designed, and implemented numerous data warehouses and BI solutions for large and small companies. In that capacity, he always had the need for ETL in some form or another. Almost out of pure necessity, he has been busy writing the ETL tool called Kettle (a.k.a. Pentaho Data Integration) for the past eight years. First, he developed the tool mostly on his own. Since the end of 2005 when Kettle was declared an open source technology, development took place with the help of a large community.
Since the Kettle project was acquired by Pentaho in early 2006, he has been Chief of Data Integration at Pentaho as the lead architect, head of development, and spokesperson for the Kettle community.
