I build full-stack software products for the South African market — from mobile apps to SaaS platforms — and ship them to real users.
About
DevKwagga is a one-person product studio based in South Africa, founded and run by Marinus Jansen van Vuuren. I design, build, and operate full-stack software products — handling everything from architecture and backend APIs to mobile apps and payment integration. All products are built for the South African market, use South African payment infrastructure, and serve real local users. All three products are built around PayFast as the payment provider.

PayFast integration across all three products
All DevKwagga products are built for the South African market and integrated with PayFast for secure, local payment processing. LekkerRaffle is built for ticket sales and operator billing. PaySlippa is built for monthly SaaS subscription payments. The Stem Co. is built for customer bouquet checkout. All three are live, production deployments serving real South African users, built around PayFast as the payment provider.
