Profile bio
About Patrick Sheehan
“... I’ve failed over and over and over again in my life. And that is why I succeed.” -- Michael Jordan (excerpt from his "Failure" commercial)My career path to becoming an offensive operator has been a journey, including software engineering and data analytics. I have mastered many skills but ultimately landed on my passion, offensive cyber operations. I’ve proven my skill multiple times: awarded two CVEs, earning over 10 industry-leading certifications including OSCP and OSEP, and conducting hundreds of internal/AD and external/web app assessments spanning years of pentesting experience. Applying over three decades of in-depth computer experience and business analytics positions me to safely identify and report on the impact of exploitable vulnerabilities, thereby preventing the next cyber threat from harming your business operations and reputation.So with that, why the quote on "failure"? In short, it's persisting, tenacity, and not giving up. Celebrate the successes (and hopefully there are many), but also adopt a model of continuous learning and continuous improvement. And preferably while always striving to maintain a sense of humor, and always remembering rule number 6.If your business could benefit from my experience (in the form of hands on offensive operations / pentesting and is remote, excellent! Bonus points if I can help mentor others grow their skillset.). Please reach out! Even if not, if you're curious about rule #6, please don't hesitate to contact me at patrick.k.sheehan@gmail.com.As a plot-twist -- Rule #6 has been rumored to have an association with the website WorldsOkayestPentester.com :)
Listed skills include Cross Functional Team Leadership, Analysis, Software Quality Assurance, Competitive Analysis, and 14 others.
