About My Journey

Hands-On IT Training at Passerelles Numériques Cambodia

I am currently pursuing an Associate Degree in Systems and Network Administration (SNAC) at PNC in Phnom Penh. PNC provides high-quality technical education to underprivileged youth with a strong focus on practical, industry-aligned skills.

My daily coursework involves configuring network topologies, troubleshooting real-world server connections (such as AWS EC2 instances, Laravel API backends, and MariaDB remote access), crimping network cables, and mastering Linux command-line operations.

Network Security

AWS Security Groups, UFW firewall, and SSH key authentication.

Troubleshooting

Diagnosing network errors, port conflicts, and service bottlenecks.
