What I'm looking for

I’m looking to build, secure, and automate enterprise networks—improving latency and reliability—while applying Cisco/Fortinet expertise and NETCONF/YANG automation in a security-focused environment.

I’m an experienced Network Engineer working with enterprise-level Cisco and Fortinet solutions, including router and switch management, VLAN design, and QoS tuning.

I’ve built, deployed, and secured network infrastructures with hands-on experience in wireless controller implementations, cloud networking, and virtualization. I focus on practical improvements that enhance performance, maintain compliance, and keep complex environments reliable.

In my recent role, I applied QoS policies to prioritize voice & video traffic to improve performance and reduce latency, while also managing Active Directory for 200+ users. I strengthened security through information security and risk management strategies and handled 10+ daily AD authentication issues via ServiceNow.

I’ve supported enterprise Cisco L2/L3 networks and maintained WLAN connectivity with Cisco 9800 WLC, while managing FortiGate 500E firewalls. I also develop network automation using Python with NETCONF/YANG (ncclient), producing XML/JSON outputs and automating discovery, extraction, event queries, and config validation.
