Resume

A compact overview of my cybersecurity, IT, communication, and project experience.

Summary

IT graduate and cybersecurity practitioner with exposure to SOC operations, GRC work, risk documentation, security tooling, and enterprise environments. Before moving into IT and security, I worked in writing, media, and communications, which turned out to be useful rather than a detour.

I am strongest where technical detail needs to become clear notes, practical documentation, or a workflow someone else can follow. I use AI tools heavily for research, drafting, automation, and project development, but I keep human review where it belongs: in charge.

Experience

Graduate Cybersecurity Analyst Intern

Worked in a professional security environment with exposure to SOC and GRC activities. Supported monitoring, investigation notes, documentation, risk tracking, and security reporting tasks. Built a practical understanding of how security operations, business risk, and compliance processes meet in an enterprise setting.

IT / Security Project Work

Built projects around dashboards, automation, AI-assisted workflows, web deployment, security research notes, and structured documentation. These projects helped me practise frontend development, workflow design, technical problem solving, and the habit of testing ideas instead of just admiring them in a notes app.

Senior Copywriter / Journalist

Worked in media, advertising, and communications before moving into IT and cybersecurity. Built strong writing, research, stakeholder communication, campaign planning, and deadline management skills. That background now helps me explain technical issues clearly and write documentation people can actually use.
