At Jaam Automation Africa, I build .NET Core APIs and backend services for a workflow platform used by lawyers and patent attorneys. I integrated iManage, K2, Inprotech, and Microsoft Graph, and built e-filing to the European Patent Office.

Before that, I maintained and extended production software for BMW Financial Services South Africa, addressing bugs and data issues affecting thousands of users. I also built a facilities ticketing system independently and create side projects that bring AI into everyday workflows.
