Security+, ISC2 CC • Red teaming & offensive security enthusiast

About Me

I am currently working towards an MSc in Computer Science with Data Analytics (expected 2026). I hold CompTIA Security+ and ISC2 CC certifications and have hands-on experience across cyber security operations, IT infrastructure, and support. My skills include threat detection, vulnerability management, and security monitoring, and I am aiming to progress into roles focused on incident response, red teaming, and offensive security. Outside of work, I run a home lab using VMware ESXi and Proxmox to practise red teaming and cyber defence in realistic environments.
