At Universitas Atma Jaya Yogyakarta, I’m studying Computer Science and focusing on cybersecurity and backend development. I explored real-world attack scenarios by building a SIEM-based lab with Wazuh.

In my system development projects, I worked through challenges in system design, debugging, and configuration. My hands-on experience includes PHP, Java, MySQL, and Linux environments.

As an Assistant Lecturer for Administration and Database at Universitas Atma Jaya Yogyakarta, I assisted with practical sessions using Microsoft SQL Server Management Studio. I guided students in designing and querying relational databases and helped troubleshoot SQL queries.

At Kantor Admisi dan Akademik UAJY, I responded to student inquiries and handled admissions and academic administration. I also instructed students in C and Java programming at Kelompok Studi Pemrograman UAJY.
