Profile Summary

A cloud-native security engineer who lives in Terraform, Kubernetes, and CI/CD pipelines. Builds automated security guardrails that scale with infrastructure growth. Has secured multi-cloud environments across AWS and GCP for high-growth SaaS companies, reducing misconfiguration incidents by over 60%.

Problems Solved

  • Designed and deployed a cloud security posture management system across 200+ AWS accounts, reducing critical misconfigurations by 65% in 6 months.
  • Built automated Kubernetes admission controllers that prevented 40+ policy violations per week from reaching production clusters.
  • Led the migration of legacy on-prem security controls to cloud-native equivalents, cutting infrastructure security costs by 35% while improving coverage.

What They Build

Builds cloud security posture management tooling, automated compliance pipelines, infrastructure-as-code security scanning, and container runtime security monitoring. Focuses on making cloud security self-service for platform engineering teams.

What Would Make Them Move

Wants a cloud-native company where infrastructure security is a first-class concern, not an afterthought. Looking for a team that ships infrastructure changes daily and needs someone to make that safe. Hybrid in Melbourne preferred.

Mission & Values

Cloud security is not about locking things down — it is about building guardrails that let teams move fast without blowing up. I automate security controls so developers never have to think about them.
