About Me

After completing an undergraduate degree in electronic engineering from Stellenbosch University, I pursued a master's degree focused on computer vision and autonomous navigation applications. I spent five years in the telecommunications and intelligence industry working on big data solutions for national governments and the law enforcement community, and two years abroad at bol.com, the largest e-commerce platform in the Netherlands, solving problems in the search and recommendations domain.

As of January 2024 I am applying my skills in software, data and machine learning engineering at primer.io rebuilding payments and commerce from the ground up.
