What I'm looking for

I’m looking for a role where I can support and improve unified communications and network services—focusing on reliable uptime, faster incident resolution, and continuous growth in telecommunications and security.

I’m an IT professional with 3 years of experience as an L2 Cisco collaboration engineer, backed by a strong foundation in IT services and customer-facing support.

I maintain and troubleshoot enterprise UC infrastructure including CUCM, UCCX, Webex, and Unity, helping reduce system downtime and improve overall efficiency for communication services.

In my recent role, I spearheaded end-user support for Cisco Finesse, Jabber, and Webex in a managed service environment, reducing average resolution time for common incidents by 30% through streamlined troubleshooting and KB enhancements.

I also improved reliability and user outcomes—creating a server-certificate change that cut certificate-related outages by 90% and ensured 99.9% uptime for critical communication services, plus optimizing media resources to reduce dropped calls by 35% and coordinating a successful switch to MS Teams for 2,000+ users (95% adoption in the first month).
