About

Professional summary

I am a Senior NOC Engineer and Cisco Voice & Unified Communications Administrator with more than nine years of experience supporting 24x7 network operations and enterprise communication environments.

I specialize in real-time network and system monitoring, incident lifecycle management, SLA adherence, root-cause analysis, escalation coordination, and operational documentation. I have supported multi-site enterprise infrastructure and collaborated closely with L1, L2, L3, vendor, carrier, firewall, and voice teams.

My unified communications experience includes administering Cisco Unified Communications Manager, Unity Connection, UCCX, and Expressway-C/E. I handle MACD activities, IP phone and user administration, voicemail services, call routing configurations, SIP trunks, voice gateways, and Mobile and Remote Access support.

I have strong networking fundamentals across Cisco routing and switching, Layer 2/Layer 3 technologies, VLANs, STP, EtherChannel, LACP, TCP/IP, DNS, DHCP, and basic Palo Alto firewall troubleshooting. I also support ISP circuit coordination, hardware RMA activities, and telecom connectivity troubleshooting involving SIP, PRI, and PSTN services.

I am experienced with monitoring and ITSM platforms including SolarWinds, ServiceNow, PRTG, Nagios, MRTG, Cacti, and Centreon. I value clear shift handovers, well-maintained SOPs, proactive monitoring, and effective communication to restore services quickly and improve operational reliability.

Experience

Career history

I monitor network, server, and voice infrastructure in a 24x7 NOC environment using SolarWinds. I manage incidents in ServiceNow from triage through root-cause documentation and workflow tracking, resolve L1-L3 issues according to SOPs, and escalate complex cases while maintaining SLA compliance.

I administer Cisco CUCM, Unity Connection, and UCCX platforms, including MACD requests for IP phones, users, extensions, voicemail, and calling features. My responsibilities include configuring route patterns, translation patterns, CSS, partitions, SIP trunks, and voice gateways; supporting Expressway MRA and Jabber issues; monitoring call-processing health with RTMT; troubleshooting voice incidents; and coordinating with carriers, ISPs, vendors, and internal L3 teams.

Senior NOC Engineer ACT Fibernet

Jun 2015 – Oct 2022

I monitored and troubleshot network incidents in a 24x7 NOC environment, addressing internet connectivity, no-browsing, and customer-reported issues within defined SLA targets. I used EVEREST, OMD, MRTG, and SolarWinds to monitor network devices and performance and proactively identify service degradation.

I supported IP pool design, IP address planning, and network migration activities. I implemented and troubleshot Layer 2 technologies including VLANs, STP, EtherChannel, LACP, and Port Security, conducted monthly network audits, and coordinated with OFC teams, field engineers, and ISPs to restore outages and support network expansion.
