I am working for a renewable energy consultancy company. I convert renewable energy expertise in user friendly digital tools. This can be an Excel workbook, website (Joomla, Mediawiki, question2answer) or (GIS based) database.

In my private time I have build a few websites. The most successful one is allepeilingen.com which compares polls of Dutch political parties. The week before the elections I received 7,000 unique visitors per day on my website.

Technologies I have experience with: MediaWiki, Joomla Component Development, REALbasic, Mathematica, Matlab, VBA, PHP, PostgreSQL, Microsoft SQL Server, MySQL, Microsoft Access, Microsoft Excel, Google Visualization API, Google Maps API and GRASS

comment excel performance: Lookup Vs Getpivotdata
I assume the pivot only has to do the aggregations only on refresh and since my base data is fixed I will not hit refresh. I only use the GetPivotData function for lookup purposes.

comment excel performance: Lookup Vs Getpivotdata
I am very familiar with ODBC links to external databases from Excel. In this case I would like to have a stand alone Excel based system and I am looking for the most efficient solution.
