Malcolm obtained his BSc (Hons) in Computer Science from the University of Pretoria in 2004 and had been part of the Computer Science Department's technical team in 2003 and 2004. After graduating he started work as a Linux Administrator in the healthcare industry where he met and worked with Nico. With an existing passion for Linux and Open Source Software, he quickly fell in love with PostgreSQL and has been working with it at numerous companies ever since. During the course of his career, he also got involved with the design and architecture of systems and infrastructure to leverage the best design possible out of the available technology.

In 2017 Malcolm spoke at the first PostgresConf conference in South Africa and subsequently at the PostgresConf in New York in 2018 and 2019 and Silicon Valley in 2019. He also co-founded TechConf, the non-profit company that now runs and organises both PostgresConf South Africa as well as LinuxConf [ZA], the Linux and Open Source conference in South Africa.
