Lead Story
Detect. Defend. Design the quiet.
An AI blue-team engineer files dispatches on detection, cloud & response.
I build at the seam of AI-driven detection, cloud security and incident response — security systems that stay invisible until the moment they need to be loud.
By the Numbers
- 50%
- Faster analyst triage
- 40+
- Sigma rules shipped
- 10K+
- Alerts triaged
The quiet discipline behind a loud defense.
An account of building defenses that stay invisible — until the very moment they must be loud.
Where I operate — from the cloud edge to the silent SOC.
Four disciplines, one mandate: keep the estate quiet and the adversary in plain sight.
Mapped to MITRE ATT&CK and NIST 800-53.
Cloud Security Architecture
Hardening AWS, Azure and GCP estates with least-privilege IAM, encrypted-by-default data planes, and continuous posture management — from greenfield rollouts to remediating exposed attack surface at scale.
Detection Engineering
High-signal Sigma and YARA rules grounded in MITRE ATT&CK, plus AI-driven Graph RAG pipelines for threat-intel correlation — cutting false positives through behavioral baselining and graph analysis.
Incident Response
Triage to recovery: containment playbooks, SIEM integration, threat-actor attribution, and post-mortems that engineering teams actually adopt. A calm hand on a hot keyboard.
AI Blue Team
LLM-powered security tooling: Graph RAG knowledge graphs for threat intelligence, AI-assisted triage, and automated detection pipelines — while securing AI systems against prompt injection and model abuse.
A record of operations shipped, not shelved.
Dispatches from the SOC floor — knowledge graphs, detections and cloud posture, shipped to production.
Argus GraphRAG
Architected a Graph RAG pipeline connecting 10K+ threat events in Neo4j, enabling LLM-assisted correlation and cutting analyst triage time in half.
Threat Intel Graph
Built a real-time threat-intelligence knowledge graph ingesting IOCs from 12 feeds, structured for graph traversal and adversary attribution at SOC scale.
QRadar SIEM Integration
Integrated QRadar with Suricata IDS and authored 40+ high-signal Sigma detection rules grounded in MITRE ATT&CK, reducing the false-positive rate by 40%.
Cloud Posture Platform
Designed a multi-cloud security posture platform using Wiz and GuardDuty, deploying deception assets that caught 3 active lateral-movement attempts in 90 days.
SOC 2 Compliance Sprint
Drove SOC 2 Type II readiness from 0 to 65% in one quarter using Vanta, mapping every control to AWS security primitives and engineering guardrails.
Secure Serverless App
Secured a production serverless application with layered WAF rules, Lambda authorizers, and zero-trust API gateway policies — passed independent pentest clean.
A toolbox kept sharp — and battle‑tested.
The instruments of the trade, each with the years logged behind it.
Production-grade tools across six disciplines.
