Message

At PT Bank Central Asia Tbk, I work in security monitoring and internal penetration testing to safeguard critical assets. I also conduct security assessments and implement mitigation strategies.

I manage 24/7 security monitoring operations to detect, analyze, and respond to potential cyber threats. I also identify and remediate vulnerabilities within internal systems.

I optimized phishing response workflows, achieving a 90% reduction in phishing-related security incidents, and design cybersecurity awareness training programs for employees.

Earlier, as an IT Specialist Intern at PT Bank Central Asia Tbk, I collaborated with software engineering teams and developed and maintained applications using Java Spring Boot and Angular. My projects include a Flask REST API and Beeverse, a social media web app built with Laravel.
