Hi, I'm David πŸ‘‹

Security Analyst & Engineer focusing on Incident Response and Cloud Security.

Profile


About

I am a Security Engineer who doesn’t trust assumptions. I build and break systems, then automate the guardrails: detections, incident response, and secure cloud architectures. My work spans AWS/GCP IAM sanity checks, log pipelines (Splunk + Elastic), PCAP threat hunting with Zeek/Suricata, and rule engineering (YARA/Sigma).
