// 01. ABOUT
Tentang Saya
Saya adalah mahasiswa Semester 3 Program Studi Teknik Informatika di Universitas Brawijaya. Aktif mengikuti berbagai kompetisi Capture The Flag (CTF) baik tingkat universitas maupun nasional, dengan fokus memecahkan tantangan decompilation, dynamic debugging, dan ekstraksi memory dump.
Selain bermain CTF, saya juga mendokumentasikan alur penyelesaian dalam bentuk writeup teknis serta membuat script pendukung untuk mengotomasi proses analisis binary.
