I'm developing a private cybersecurity assessment platform for authorized enterprise network security evaluations, including automated Python workflows and structured executive and technical reporting.

In my home cybersecurity laboratory and through Hack The Box's Penetration Tester Job Role Path, I perform network and service enumeration, vulnerability assessment, web application testing, controlled exploitation, evidence collection, and reporting. I'm also building my Active Directory fundamentals.

I use Nmap, Wireshark, Burp Suite, Metasploit, Linux, Windows, Python, and Bash to identify and validate security weaknesses.

I bring 15+ years of engineering and operations leadership in renewable energy, where I led multidisciplinary technical teams, troubleshot complex electrical, mechanical, and control systems, and produced technical documentation. I'm seeking a remote penetration testing role where I can apply structured problem-solving and evidence-based reporting.
