I’m a Cyber Security student at Binus University and a member of the Binus IT Division Associate Member Program, working as a System Analyst. My responsibilities include troubleshooting systems and working with databases. I also explore web security through personal projects and CTF challenges. Right now, I'm very interested in network security and vulnerability assessment and currently looking for an internship to gain more hands-on experience in the field.

01 — About
Curious by default. Practical by choice.
I’m currently studying Cyber Security at Binus University Jakarta and expect to graduate in 2028. Alongside university, I work part-time as a System Analyst at Binus, where I troubleshoot system issues, investigate data and logs, debug frontend problems, and communicate with developers.
My security practice includes web exploitation, vulnerability analysis, CTF challenges, and security-focused research. I’m interested in growing toward Cyber Security Analyst, Security Engineer, Network and Security, and DevSecOps roles.
