●Applied a methodical, process-driven approach to complex operational challenges, building a strong foundation for structured cybersecurity analysis and incident response.

Cybersecurity Analyst I

Surgery Partners – Irvine, CA March 2022 – August 2022

Assisted in triaging and analyzing security events from email security, IDS, and endpoint tools, escalating incidents per NIST-aligned processes.

Supported the operational execution of investigative playbooks and contributed to the tuning of SOAR automation workflows.

Participated in an on-call rotation, providing support during off-hours and critical incidents.

PROJECTS & HANDS-ON EXPERIENCE

Defensive Cyber Operations (DCO) Simulation: Worked with a small team to analyze log data in Splunk and Kibana/Elastic Search, hunting for threat signals and pulling out adversary IOCs from large datasets during a simulated DCO exercise.

Vulnerability Management & Risk Analysis: Practiced identifying and assessing network vulnerabilities, then used the MITRE ATT&CK Framework to break down adversary TTPs and suggest practical countermeasures—essentially simulating what it takes to maintain a solid security posture.

Threat Hunting & Incident Response: Ran threat hunting exercises based on SANS FOR608 techniques, walking through how to reconstruct security events, spot gaps in coverage, and dig through machine data for signs of potential threats.

Automation & Security Tooling: Took repetitive data analysis tasks and built out PowerShell and Bash scripts to automate them—cutting down on manual work, reducing mistakes, and helping speed up response during mock incident scenarios.

ICS/SCADA Security Analysis: Spent time with SANS ICS 410 materials to better understand the unique security challenges in industrial environments, building a foundation for how to approach risk and protection in critical infrastructure.
