Resume

A short overview of my IT support, technical support, cybersecurity, backend troubleshooting, documentation, and project experience.

IT SupportTechnical SupportCybersecuritySOCGRCTechnical Writing

IT and cybersecurity graduate based in Hobart, Tasmania. Experience across IT support, Microsoft 365, backend troubleshooting, security operations support, GRC documentation, homelab automation, and technical writing.

Recent projects include a Docker-based OpenClaw Security Hub, a public Threat Intelligence Dashboard, a Coastal Fishing Forecast engine, and this Next.js/Payload/Vercel portfolio.

Before moving into IT, I worked in media, copywriting, and automotive journalism. That background helps me ask sharper questions, write useful notes, and explain technical information to different audiences.
