01 — About

I build security detections, investigate threats, and strengthen the infrastructure behind them.

My work spans SOC operations, SIEM engineering, incident triage, and cloud-native infrastructure. I turn raw telemetry into actionable detections and build automation that makes security operations more reliable and easier to investigate.

03 — Approach

From telemetry to action.

Effective security operations start with trustworthy log collection, useful detection logic, and a clear path from an alert to an investigation. My experience covers that workflow across QRadar, endpoint tooling, and response automation.

Collect

Onboard and normalize log sources so analysts can trust the evidence behind each alert.

Detect

Write and tune QRadar rules and reports with AQL and Regex, aligned to MITRE ATT&CK.

Respond

Investigate phishing, DDoS, and malware activity with endpoint and response tooling.
