What I'm looking for

I’m looking to apply my LTE, 5G, WAN, and telecom troubleshooting experience in a high-availability network environment where I can lead escalations, improve automation, and mentor engineers.

I’ve supported LTE, 5G, WAN, and telecom infrastructure for AT&T, T-Mobile, Verizon, Vodafone, and BSNL across geographically distributed, high-availability environments.

At Mastec Services, I served as a senior escalation point for Ericsson LTE and 5G integration, leading root-cause analysis, validation, parameter audits, alarm monitoring, and post-deployment support. I developed Moshell and automation scripts to streamline 5G SA configuration and restore service across multi-site production environments.

I’ve also led OSS/BSS, Wi-Fi core, switching, migration, roaming, and signaling work across Ericsson, ALU, NSN, and Nokia platforms. I bring CCNA certification, hands-on routing and WAN troubleshooting, and a collaborative approach to mentoring engineers and resolving complex network issues.
