What I'm looking for

I seek a senior network or systems role where I can lead infrastructure projects, improve network reliability and security, mentor teams, and apply my VoIP and LLM annotation experience.

I am a Senior Network Engineer with 14 years of experience in project management, LAN infrastructure design, implementation, and troubleshooting across enterprise environments.

I have deep expertise in Cisco (CCNP R&S), Aruba, HP, 3Com technologies, wireless design, VoIP (Elastix/Issabel, Grandstream, Polycom), IP cameras, and network security, and I led teams supporting more than 1,000 users.

I also bring server and systems administration skills (Active Directory, ADFS, Office 365, Ubuntu), experience in LLM data annotation and evaluation projects, and a record of implementing backup, monitoring and security solutions to improve reliability and performance.
