Message

At Dariel, I provide ongoing support and enhancements for Sanlam Corporate’s Claims Portal in the Retirement Fund Annuity Division. I also assist with mentoring graduates and technical interviews.

Earlier, I worked on Sanlam Corporate’s Broker and Claims Portals, contributing to the Two-Pot Retirement System and migrating functionality from a legacy portal. At Wardew Design and Automation, I programmed industrial and building automation systems, including a mineral-sorting algorithm that saved the company about R40 million in machines for a mining site.
