Profile Summary

A detection engineer who treats security detections as software. Builds end-to-end detection pipelines with automated testing, version control, and CI/CD deployment. Has built detection programs from scratch at two high-growth companies, reducing mean time to detect from days to minutes.

Problems Solved

  • Built a detection-as-code pipeline that automated the testing and deployment of 500+ detection rules, reducing false positive rates by 40% and deployment time from days to minutes.
  • Designed a threat hunting program that identified 3 previously undetected intrusion campaigns within the first quarter of operation.
  • Automated alert triage for the top 20 highest-volume alerts, reducing SOC analyst workload by 50% and improving mean time to respond by 65%.

What They Build

Builds detection-as-code frameworks, automated alert triage systems, threat hunting playbooks, and SOAR integrations. Focuses on reducing analyst fatigue through high-fidelity detections and automated response workflows.

What Would Make Them Move

Looking for a company that treats detection engineering as a proper engineering discipline, not just a SOC analyst writing Splunk queries. Wants to build a detection program with real CI/CD, testing, and metrics. Hybrid in Sydney.

Mission & Values

Most detection engineering is just writing SIEM rules and praying. I build detection-as-code pipelines that test, version, and deploy detections like software — because that is what they are.
