What I'm looking for

I am looking for opportunities that allow me to further develop my skills in cybersecurity while contributing to a team-focused environment that values continuous learning and innovation.

I am a dedicated Security Professional with hands-on experience in vulnerability assessments and penetration testing across various platforms, including web, network, system, and mobile. My passion lies in discovering zero-day vulnerabilities and effectively communicating risks to enhance organizational security posture. I have a proven track record of leading and mentoring junior testers while promoting secure development practices.

Throughout my career, I have successfully performed black-box, gray-box, and white-box penetration testing, developed automation scripts for efficient testing workflows, and conducted both dynamic and static analysis for web and mobile applications. My experience includes working with diverse teams to assess AWS-based cloud infrastructures and implement security measures, ensuring compliance with regulatory standards and translating technical risks into business language for leadership.
