What I'm looking for

I'm looking to grow in an offensive security role.

At ECOM College, I completed 450+ hours of hands-on training in offensive security, including black-box web application and infrastructure assessments. I practiced reconnaissance, enumeration, exploitation and privilege escalation across Linux and Windows environments.

For my final cybersecurity project, I identified authentication bypass and file-read weaknesses that led to remote code execution and Linux privilege escalation, then documented evidence and remediation. In a separate Metasploitable 2 lab project, I validated vulnerabilities and documented findings in a penetration testing report.
