About

Boardroom strategy, keyboard execution

I'm a dual-track IT and cybersecurity leader who operates fluently at both the boardroom and the keyboard — shaping enterprise architecture strategy while hunting adversaries across hybrid and multi-cloud environments. My work fuses GRC, detection engineering, incident command, and infrastructure modernization into programs that measurably reduce risk and accelerate the business.

Impact

Measurable outcomes

Delivered across governance, operations, and security engineering.

Incident Command

Carry a 24×7 on-call rotation and act as Incident Commander on critical security events, coordinating technical, legal, and executive stakeholders through containment, eradication, and recovery — driving blameless post-mortems that reduced repeat incidents by 40%.

Detection Engineering

Built SIEM and EDR detections mapped to MITRE ATT&CK across endpoint, identity, cloud, and network domains; closed prioritized coverage gaps surfaced through hypothesis-driven threat hunting and purple-team exercises — cutting MTTD on high-severity alerts by ~35%.

Automation & Enrichment

Engineered SOAR-style playbooks and Python / PowerShell enrichment workflows that cut analyst triage time by ~50%, raised signal quality on high-priority alerts, and lowered MTTR for common intrusion patterns.

Governance That Scales

Built compliance programs aligned to SOC 2, HIPAA, NIST, and CISA guidance — decreasing audit exposure by 60% and lowering security incidents by 25% while enabling faster releases via policy-as-code.

Operational Excellence

Established formal Change Advisory Boards and vendor-governance frameworks that cut unplanned outages by 45% and tightened oversight of third-party access — turning IT from a cost center into a reliability engine.

Cloud Transformation

Drove Zero-Trust, cloud, and AI adoption across complex environments — improving operational efficiency by 40% while preserving guardrails for data, model, and identity governance.

Expertise

Where I focus

Translating adversary TTPs, enterprise risk, and architectural choices into outcomes that boards, engineers, and auditors can all align behind.

Enterprise Architecture

Modular, future-proof blueprints across compute, network, identity, and data — designed for scale, reliability, and change.

Cloud Security

AWS, Azure, and GCP landing zones, CSPM (Wiz, SCC), container security, and cost governance for predictable performance at enterprise scale.

Cyber Risk Management

Cyber risk quantification, executive-facing risk metrics, BCP/DR, vendor risk, and program leadership translating detection efficacy into board-level decisions.

Threat Hunting

Hypothesis-driven hunts fusing telemetry from SIEM, EDR, and IDS/IPS with open-source, commercial, and internal threat intelligence — tracking adversary TTPs mapped to MITRE ATT&CK.

AI Security & Enablement

AI governance, secure LLM adoption, adversarial AI and agentic threat modeling, and guardrails that let organizations move fast with AI without moving carelessly.

Team & Vendor Leadership

High-trust cultures, clear operating models, and vendor ecosystems aligned to measurable business outcomes — mentoring teams to >99.9% SLA adherence.
