About Nicholas O'Sullivan
Over 15 years making technology make sense for the people who lead organisations.
Suburban Australia is the broader business identity behind digital projects, technology advice and community-minded services. Security-focused work has its own home now, under Suburban Secure.
I bring more than 15 years of hands-on IT experience across small business support, school environments, Queensland Government systems, church infrastructure and community governance. My focus is practical: understand the problem, choose a sensible path, implement carefully and document what was done.
- Experience with Microsoft 365, Google Workspace, Windows, Linux, virtualisation, cloud and containerised systems.
