I'm the Technical Director at Erzo, which started in Johannesburg in 2010, and I work as a Fractional CTO for businesses that need senior technical leadership without a full-time hire. I'm based between Cape Town, Johannesburg and Durban, working with clients in South Africa, the UK and the US.
Most of my work lives in private client repos, so this page sums it up without naming names.
