What I'm looking for

I am seeking a role that allows me to grow in cybersecurity, focusing on risk assessment and vulnerability management while contributing to a collaborative team environment.

I am a 4th-year Cyber Security undergraduate at the Sri Lanka Institute of Information Technology, currently maintaining a 3.1 CGPA. With six months of hands-on experience as an Information Projects Security Engineer, I have developed a strong foundation in various cybersecurity frameworks and practices. My passion lies in enhancing security measures and contributing to impactful cybersecurity initiatives.

Throughout my academic and professional journey, I have successfully rebuilt a secure mobile app with two-step NFC verification and conducted on-site risk assessments that uncovered vulnerabilities, driving mitigation through multi-factor authentication and automation. I have also reverse-engineered Android applications to enhance security features while preserving encryption integrity, showcasing my commitment to ethical cybersecurity practices.
