Multi-node · Self-hosted · Always evolvingLuis Cisneros · Junior Network Engineer
I build networks
that hold up.
Cisco switching, secure connectivity, packet-level troubleshooting, and a repair background that taught me to follow every signal to the source.
Connect the signal. Find the fault. Make it reliable.
01 / About
Network minded.
Hands-on by nature.
I’m Luis, a junior network engineer with more than five years of hands-on IT experience supporting connectivity, infrastructure, endpoints, and the people who rely on them.
My work spans Cisco switching, firewalls, VPNs, VLANs, LAN/WAN troubleshooting, packet analysis, and monitoring. Years of board-level repair shaped the same approach I bring to networks: isolate the fault, validate the path, and document the fix.
