Hi! I'm Alif Raafiansyah Pratama, an Informatics student, Network Engineer, and Cyber Security Enthusiast passionate about building secure, reliable, and optimized digital infrastructure. Combining a solid foundation in computer networking (TKJ) with hands-on experience in enterprise-level environments like Diskominfo, I specialize in designing robust systems, managing dynamic routing, and implementation of network security defenses. Beyond core networking, I actively expand my technical horizon into data science and artificial intelligence while conducting continuous research in web penetration testing and vulnerability assessments—ensuring systems are not just operational, but secure from the ground up.
