Nicholas “Nick” O'Sullivan
IT consultant in Townsville
I help businesses, schools and community organisations make confident IT decisions, improve security and deliver upgrades with minimal disruption.
I'll explain the options and costs, plan changes with the people affected, and leave clear documentation for whoever manages the systems next.
Practical help with your technology
- Reliable connections: plan internet upgrades, improve Wi-Fi and connect your buildings.
- Safer systems: protect accounts and information, review backups and make sense of security alerts.
- Better decisions: compare quotes, choose suitable equipment and plan improvements around your budget.
Experience you can explore
I've spent more than 17 years working in IT across small business, education and community organisations. My work includes planning moves to fibre internet and replacing firewalls with minimal interruption.
