• Mentor analysts and support incident response operations across Tier 1–3 teams.
• Lead post‑incident reviews and contribute to continuous improvement of IR processes, tooling, and operational standards.
• Produce high‑quality technical and executive‑level reports and recommendations.
• Drive automation and operational efficiency through scripting and security engineering improvements.

• Deep knowledge of raw forensic artifacts and operating system internals (Windows, Linux, macOS), with the ability to manually parse and validate artifacts independently of commercial DFIR tooling (MFT, Registry, EVTX, Prefetch, Amcache, Shimcache, SRUM, USN Journal, browser artifacts, memory structures, file system metadata, and timeline reconstruction)
• Detection Engineering & Threat Hunting
• SIEM/XDR and EDR platforms
• Network traffic analysis and network forensics
