IT Support & Network Technician with a cybersecurity home lab, based in Gauteng, South Africa. For eight years I've been the whole IT department of a 24/7 hotel. Now I build the training tools I wish I'd had.
| CCNA Simulator · code | Browser-based network lab for the CCNA 200-301: IOS-style CLI, packet capture, 64 graded labs across all five blueprint domains, and a practice exam scored out of 1000 |
| Shift One · code | Help desk simulator graded on what you actually fixed: live phone calls, an Active Directory-style directory, remote desktop, a server room, plus an MSP service coordinator mode |
| A+ PBQ Trainer · code | CompTIA A+ 220-1201 performance-based question simulator: drag and drop, ordering, SOHO router and BIOS config sims, a Windows command-line lab, partial credit scoring and a timed exam mode |
All three are free and run in the browser. I design the scenarios, labs and grading, and build with Claude Code.

- ConnectWise PSA Tutorial: seven-lesson beginner guide to PSA ticketing, opportunities, projects and reporting

- iPhone that would not boot: layered elimination across four failing layers, device-state identification via USB product IDs, and the hypotheses that proved wrong
