Profile Summary

This Senior Security Engineer builds robust and scalable infrastructure security solutions, focusing on cloud environments and automated defenses. They are adept at designing and implementing security controls that protect critical assets and enable secure development practices across large-scale platforms. Their work directly contributes to strengthening the security posture of high-growth technology companies.

Problems Solved

  • Architected and deployed a multi-account AWS security baseline, reducing critical misconfigurations by 75% across 50+ production accounts at a major Australian tech company.
  • Developed and integrated a custom security policy-as-code framework using Open Policy Agent (OPA) for Kubernetes, preventing 90% of non-compliant deployments before they reached production.
  • Implemented automated incident response playbooks for common cloud security alerts, decreasing average mean time to remediation (MTTR) by 60% for infrastructure-related incidents.

What They Build

They build secure cloud infrastructure, automated security pipelines, and resilient defense-in-depth strategies. Their focus is on creating preventative and detective controls that scale with dynamic cloud environments, often leveraging Infrastructure as Code (IaC) and cloud-native security services.

What Would Make Them Move

Looking for a senior infrastructure security role in a company with real scale — millions of requests, complex networking, multi-cloud. I want to work with engineers who understand distributed systems, not just tick compliance boxes.

Mission & Values

Infrastructure is the foundation everything else sits on. If your network is not secure, nothing else matters. I am obsessed with getting the fundamentals right before chasing the shiny stuff.
