Beyond the Code.
Developer. Problem Solver. Technology Enthusiast.
Keagan van Rooyen
Software & IT Systems Developer
I build software and keep the systems around it running — and I care most about the point where the two meet a real business problem.
My foundation is formal: three consecutive National Certificates at CTU Training Solutions, moving from systems development (NQF 4) through software development (NQF 5) to cybersecurity (NQF 6). That sequence shaped how I think — first how systems fit together, then how to build them well, then how to keep them safe.
My first production work came during work-integrated learning at Axxess DSL, where I built a laundromat management application in PHP and MySQL. It taught me that a data-driven application is only as useful as the workflow it supports.
I then spent time as a financial advisor at Sanlam. It wasn't a detour so much as a crash course in sitting across from people, understanding what they actually need, and explaining complex products in plain language — skills I now use every time I scope software with non-technical colleagues.
Today, at Trihedron Group, I work across the whole stack of a growing engineering business: building and maintaining software, administering Microsoft 365 and cloud services, troubleshooting infrastructure, and finding work that should be automated. I use AI-assisted development deliberately, as a way to move faster without lowering the bar.
