OData and SAP Gateway

Carsten Boennen received his M.A. in Computer Linguistics and Artificial Intelligence in Germany in 2001 and started working at SAP that same year. Initially a Java developer and trainer, he soon became a consultant and led strategic projects in the then-new field of enterprise portals. By the end of 2002, he became a product manager for SAP NetWeaver Portal. A year later, he took on responsibility for a new product, which later became known as Visual Composer; subsequently, he managed the complete UI topic in this area. Looking for a new challenge in 2008, he joined the Microsoft Strategic Alliance Management group, which oversees the strategic alliance between SAP and Microsoft. Carsten remained in this role for four years before he joined the SAP NetWeaver Gateway product management team in 2012. Beyond his business-specific activities at SAP, he founded the first SAP karate group in 2005, which he continues to lead today.
