Security (SQL Injection, XSS)
Transitioning U.S. Marine Corps veteran and certified cybersecurity professional with hands-on experience in ethical hacking, penetration testing, vulnerability management, and incident response. Recently completed an intensive Cybersecurity Bootcamp at Evolve Security Academy (Evolve Security Certified Professional – ESP, Dec 2025), where I conducted comprehensive risk assessments, built custom Python and Bash automation scripts, performed server assessments using Kali Linux, analyzed logs with Splunk and Wireshark, deployed AWS cloud environments, and executed real-world social engineering/phishing campaigns.
Delivered professional penetration testing services for BoardSource.org, identifying critical vulnerabilities through external and internal testing and presenting findings in an 85-page executive report with prioritized remediation recommendations. Proficient across the OWASP Top 10, SIEM operations, threat analysis, malware analysis, web application security (SQLi, XSS), network security, and cloud security best practices. Leveraging four years of disciplined military service as a Radio Operator
— including satellite communications, RF signal management, network configuration, equipment troubleshooting, and mission-critical transmission monitoring — I bring proven abilities in high-pressure environments, rapid problem-solving, teamwork, and meticulous attention to detail.
Eager to apply advanced cybersecurity expertise and a strong operational foundation to protect organizational assets, detect and mitigate threats, and contribute to a forward-thinking security team. Experienced with operating and maintaining radio communication systems. Uses advanced knowledge of signal transmission and reception to ensure uninterrupted communication. Track record of enhancing team efficiency and maintaining high standards of operational readiness.
Established and maintained secure satellite and
radio communications networks in high-stakes
environments, ensuring uninterrupted mission-critical voice and data transmission across diverse terrains.
