Dion Patelis is the lead engineer at 7rocks. He completed his studies in electrical power and industrial computer systems engineering in 2012. The industrial computer systems had a heavy slant toward control systems and chemical process engineering. Before going to Murdoch University in Western Australia he worked in computers repairing and building networks using a mesh of Linux, Mac and Microsoft systems. He also spent much time developing business database systems using PHP and MySQL.

In his early working years he started as a sign writer and graphic artist creating airbrush murals on boats, cars, building and anything else paint could be applied to. He used to spend a lot of time drawing and designing machines. This made engineering a natural progression as it extends the paintbrush tool set to include that of applied science and mathematical paintbrushes. Thus he can now realise what he could only once paint as a concept on canvas.
