Wesley Lynch is one of a number of people who accidentally discovered that their real skill lay in computers. While studying chemistry at UCT, he was doing his friends’ computer science projects for fun.

“In hindsight, I’m not sure why I did chemistry,” he says. “But I’ve been interested in computers from a very young age. My dad got me a ZX Spectrum at age six and I was typing in listings from magazines to make games. When I was at UCT, I should have realised chemistry wasn’t for me. I didn’t click that I could make computers into a job.”
