Infrastructure and systems engineer moving into cyber security
Twenty-two years building and running the systems organisations depend on — from assembling the hardware, to administering the network, to specifying the room it all sits in. I am completing an MSc in Computer Science with Cyber Security at the University of York, where my research asks not whether multi-factor authentication works but whether people keep using it. Alongside that I ship production software: three side projects are live and publicly reachable, one of them served from hardware I own and administer. A Bachelor of Accounting sits underneath all of it, so I can also read the numbers the systems are carrying.
Experience
- Jan 2025 – Jan 2027
MSc Computer Science with Cyber Security (part-time, online)
University of York, UK
- Studying part-time and online alongside full-time work, graduating January 2027.
- Research topic: a task-based usability evaluation of TOTP, FIDO2 security keys and SMS codes — measuring whether people keep using a second factor, not whether it works.
- Oct 2022 – present
IT & Student Support Officer → Campus Coordinator
Canterbury Institute of Management, Darwin
- First point of contact for students and staff on the Darwin campus: hardware, accounts, classroom AV and everyday faults, resolved before they turn into tickets.
- Responsible for campus IT — workstation builds and rebuilds, peripheral and communication device setup, network and connectivity troubleshooting.
- Campus administration alongside the technical work: student records, database reporting and reconciliation — the half of the role the accounting degree turned out to be for.
- Oct 2020 – Oct 2022
IT Systems Consultant (freelance)
Sonadezi · Dong Nai Tourist · DOST Dong Nai · Agent Hai Pty Ltd
- Server, network and VPN administration for corporate and government clients, carried out remotely alongside full-time study in Darwin.
- Web hosting and colocation, including the day-to-day administration that keeps a small client estate running without an in-house team.
- Oct 2010 – Nov 2019
Director / IT Project Manager — own IT company
Equatorial Technology JSC (E-Tech), Vietnam
- Ran the company: scoping, quoting and delivery as well as the technical work — the point at which "technician" stopped describing the job.
- Server, VPN and network administration for provincial government and corporate clients, plus web hosting and colocation.
- Hardware supply and build, communication device installation, and the support relationship that comes after the invoice.
- Oct 2003 – Sep 2010
IT Technician
Dept. of Science & Technology, Dong Nai Province
- Built and ran the department's server room — conditioned power, cooling, suppression, and a virtualisation layer that took the core applications off individual machines.
- Worked on the city-wide network for the People's Committee and its ward offices, and the interprovincial data link to VDC Ho Chi Minh City.
- Converted the department's main meeting room to a digital one: conferencing hardware, audio processing tuned to the room, and a single tablet surface controlling lighting, screens and cameras.
