Mostafa worked as a test coordinator at CHOICE until 2024, focusing on testing fridges in our NATA accredited thermal lab. He was always developing unusual, intuitive and creative tests and verification methods to test the performance of products, because of his love of design and engineering.

Mostafa has a Masters in Mechanical Engineering from the University of Southern Queensland. His background is in design and manufacturing of electricity meters and domestic refrigerators, and he's also managed a commercial refrigeration testing lab and worked as a compliance engineer. He is an adept CAD and CAE engineer with experience in Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD).

Outside of CHOICE, Mostafa enjoys martial arts and has done both aikido and hapkido. He also likes CNC machines, specifically 3D printers and routers. He's the father of four boys and loves running around with them and showing them things on his 3D printer.
