I keep networks, servers and the people who depend on them running—then take the same systems discipline into research and product engineering. I do not stop at the idea. I frame the problem, build the artefact, test the weak points and take it into the real world.

Profile
I'm a proactive, detail-oriented IT engineer with a ten-year track record across telecom and enterprise IT — from NOC monitoring desks to offshore vessel server rooms. I've spent my career at the intersection of network infrastructure, security, and end-user support: the layer where technical decisions meet the people who actually rely on them.
My work spans firewall administration, network diagnostics, hardware lifecycle management, and IT service management under ITIL and ISO frameworks — always with an eye on documentation, because a system nobody can explain is a system nobody can fix at 2am.
I'm currently Senior IT Systems Administrator at The Free Press of Namibia / The Namibian, and Namibia Media Trust at large — active in the role since 20 July 2026, and rebuilding the department's infrastructure documentation and network from the ground up. Beyond operations, I publish design science research and build production-grade Namibian digital products through a research-led engineering practice.
