About

I am a cybersecurity professional currently studying toward a BSc (Hons) Cyber Security, with certifications including CompTIA Security+, Microsoft AZ-900, and HashiCorp Terraform Associate.

I combine hands-on security operations, cloud infrastructure, and DevSecOps experience with 25 years in safety-critical electrical engineering and site management.

I have experience investigating multi-host incidents, analyzing SIEM telemetry, building secure CI/CD pipelines, and securing AWS infrastructure with Terraform.
