Mark Walker has been working with computers since a very early age, starting out with programming the Sinclair ZX Spectrum. After graduating from Cardiff University, he moved to France, starting a 17-year (so far) career in SAP development, first on the SAP ERP, then moving to SAP BW in 2004. He specializes in process optimization, especially in the SAP BPS and BI-IP modules. He's been following SAP HANA since its release in 2011, and is a certified HANA Application Associate since early 2012.

Mark has been working for the last six years for Censio, a consultancy in Paris, France, which has expertise in SAP, Microstrategy, Business Objects, and Microsoft BI technologies. During that time he's worked on several end-to-end projects for some prestigious clients, and done some missions in SAP's name.

In November 2012, he published SAP HANA Starter, Packt Publishing, a small book about getting a foothold in the SAP HANA world.
