Technology explained simply.

I’m Gavin, the person behind Wiznerd Tech Services. When you call Wiznerd, you speak directly with me—not a call centre or a generic support desk.

My professional technology career began in the late 90s with hands-on computer servicing, upgrades and onsite installations. From there, I progressed through technical support into senior network and systems engineering roles with Optus and AsiaOnline Australia. AsiaOnline’s Australian business was later purchased by Nexon Asia Pacific.

At Optus, AsiaOnline and Nexon, I worked on the backbone networks supporting large-scale internet services. This included configuring and maintaining Cisco routers, managing Unix systems, and troubleshooting complex network and customer problems. At Nexon, I was the head network engineer with primary technical responsibility for the Australian backbone network and much of its associated Unix infrastructure.

My work included maintaining business-critical systems, network redesigns and upgrades, and supervising a major Sydney data-centre relocation. It taught me to investigate problems methodically, remain calm under pressure and take responsibility for seeing an issue through.

I later spent many years running my own photography business, working personally with approximately 2,000 wedding clients and managing demanding digital workflows, backups, archives and final delivery.

Today, I bring that combination of technical experience and personal service to homes and businesses throughout the Illawarra and Southern Highlands. Whether the problem is a troublesome computer, unreliable Wi-Fi or an entire business network, I’ll explain what is happening clearly and recommend the most sensible solution—without jargon or unnecessary upselling.

From the simplest question to a complex technical fault, you’ll receive the same patience, careful attention and straightforward advice.
