Bio After Roelof Temmingh completed his degree in electronic engineering he worked as a software developer and later as system architect at company that made encryption devices for the South African government. After 4 years he left the company (with @charlvdwalt) to start SensePost from his bedroom. For 7 years he hacked many networks, wrote many books, and spoke at all the conferences. He left the company in 2007 to start Paterva – the company that brought Maltego to the world. Roelof was the inventor and driving force behind Maltego for the first 10 years. Here he made many graphs, spoke at the remaining conferences, and trained many people. When he left Paterva he pondered, painted (bad.rip), made a short film (fliptheverse.com), and baked for a bit before starting a new venture called Vortimo, software that enhances the browsing experience (for investigators, researchers).
