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.

GPON Fiber Access
Linux Infrastructure

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.

Tools I work with.

A practical stack covering routing, access networks, remote connectivity, monitoring, and server operations.
