01 / About

Built around networks.

I’m Christian Ghed Caronongan, focused on networking, internet infrastructure, routing, fiber systems, and Linux-based services. I enjoy solving connectivity problems and building systems that stay practical, stable, and easy to manage.

I like turning complex network problems into clean, reliable systems.

My work centers around routers, switches, VLANs, subscriber access, GPON deployments, secure tunnels, monitoring, and server administration.

02 / Selected Projects

Infrastructure work.

Selected areas I work with — from upstream routing and fiber access to remote connectivity and server-side infrastructure.

01
MikroTik Routing Failover

Multi-WAN Routing

Resilient routing with failover, policy-based routing, PCC load balancing, NAT, and traffic management across multiple upstream links.

02
GPON Fiber OLT / ONU

Fiber Access Network

Subscriber provisioning, VLAN service mapping, bridge mode, OMCI, optical diagnostics, and fiber access troubleshooting.

03
Linux Ubuntu Services

Linux Infrastructure

Ubuntu-based hosting, storage, monitoring, web services, and practical server administration for network operations.

04
VPN Site-to-Site Remote Access

Secure Connectivity

Connecting remote networks using secure tunnels while handling route selection, dynamic WAN conditions, and cross-site access.
