I am an IT student passionate about networking, system administration, and cybersecurity. I learn by building, practicing, and solving real-world technical problems.
Dedicated IT student specialized in infrastructure, secure networking, and server systems administration.
Passerelles Numériques Cambodia (PNC)
I am currently pursuing specialized training in **System & Network Administration & Cybersecurity (SNAC)** at Passerelles Numériques Cambodia. My focus is centered on configuring robust networking architectures, securing Linux/Windows server infrastructures, and performing security vulnerability assessments.
Through hands-on practical lab environments, I configure routers, firewalls, DNS/DHCP servers, VPNs, and Active Directory domains. I enjoy taking on complex technical troubleshooting and automating daily system maintenance tasks.
Practicing with PfSense, Cisco Packet Tracer, and GNS3 daily.
Hardening systems against attacks & monitoring traffic logs.
"A secure network isn't built in a day—it is forged through continuous monitoring, rigorous testing, and proactive system hardening."
Core technical skills honed through practical SNAC curriculum labs and independent technical projects.
Designing and configuring reliable IPv4/IPv6 networks and VLAN structures.
Deploying, hardening, and maintaining Linux and Windows server environments.
Protecting network perimeter, managing firewalls, and security auditing.
VMware ESXi, VirtualBox, Docker containers, GNS3 simulation, Cisco Packet Tracer, Git, and Markdown documentation.
Real hands-on labs and network infrastructure designs completed during SNAC training.
Designed and simulated a multi-building enterprise network featuring segmented VLANs, Inter-VLAN routing, OSPF dynamic routing, and redundant spanning-tree protocol (STP).
Configured a high-security pfSense edge gateway with Snort IDS/IPS threat detection, Squid proxy filtering, and Site-to-Site IPsec VPN tunnel for remote site connection.
Deployed automated Linux server stack running Nginx reverse proxy with SSL certificates, Postfix/Dovecot secure email server, and automated backup Bash scripts.
Solid academic background in IT system & network administration.
Intensive technical education covering Cisco networking principles, Linux/Windows administration, cloud computing, cybersecurity defense strategies, soft skills, and professional English.
