What I'm looking for

I'm looking for a cybersecurity internship where I can apply hands-on skills in digital forensics, network defense, secure infrastructure, access control, and vulnerability assessment.

I've built a dual-stack network simulation in Cisco Packet Tracer, managing IPv4/IPv6 connectivity through OSPF and hardening access with SSH and RADIUS authentication.

I'm pursuing a Bachelor of Computer Science (Hons) in Cybersecurity at Multimedia University, Cyberjaya. My hands-on work includes digital forensics with Kali Linux, metadata analysis, hexadecimal inspection, vulnerability evaluation, and maintaining data integrity.

I also developed a TGV Cinema relational database system in openGauss, designing a normalized 10-entity ERD and implementing SQL triggers and stored procedures to automate transaction logic and prevent data tampering. I'm eager to apply network defense, system hardening, and forensic investigation skills in a cybersecurity internship.
