Security engineer with 7 years of hands-on delivery across detection engineering, threat intelligence automation, cloud incident response, and enterprise DLP. I build security systems that generate measurable outcomes — not just compliance checkboxes. Currently leading security engineering at Payatu and building FreeIntelhub as an open threat intelligence platform.

Side Project

FreeIntelhub — open threat intelligence platform

Mission

I design security architectures that connect identity, telemetry, detection logic, and response workflows into resilient systems with measurable operational impact.

Engineering Philosophy

I approach security as a systems engineering problem. Architecture decisions should define where trust boundaries exist, how telemetry is generated, and how detections flow into repeatable response outcomes.

My work spans security architecture, detection-as-code, automation pipelines, and incident response engineering — always grounded in clear design principles and practical SOC execution.

Working Principles

  • Detection-first: every control should improve real detection or response outcomes.
  • Automation over repetition: remove manual bottlenecks before scaling teams.
  • Evidence-driven engineering: tune using telemetry quality, precision, and analyst feedback loops.
  • Operational clarity: ship playbooks and runbooks with every technical implementation.

Security Architecture Philosophy

Security should be built, not just audited.

  • Risk-aligned architecture
  • Defence-in-depth design
  • Detection-driven engineering
  • Cloud-native security principles
  • Control maturity alignment
