My background includes threat hunting, incident response, SOC alert triage, SIEM/SOAR, EDR/XDR, vulnerability management support, cloud security alerts and security documentation.

I do not use or share confidential internal data from previous employers. Any samples I provide are sanitized or created as demo materials. If you need someone with real enterprise IT and cybersecurity experience who can troubleshoot, analyze and document clearly, I can help.
