As a Penetration Tester since March 2024, I identify and exploit vulnerabilities in systems, networks, and web applications. I perform comprehensive security assessments, including vulnerability scans and manual testing. I use tools like Burp Suite, Kali Linux, and Metasploit to simulate attacks, identify risks, and recommend remediation strategies. I also document findings and provide actionable reports to improve overall security posture for clients and internal teams.
