• Started at the first tier of the on-call escalation chain for Iridium’s prepaid and safety services, learning both under a mentor.
• Moved from running procedures to writing them. I plan, write, and execute my own updates and infrastructure changes.
• Lead the legacy services side of my team, providing technical direction across Iridium’s legacy circuit-switched voice and data services.
• Drive the migration of those services to SIP while maintaining interoperability with 2G technology. Two services migrated to date, with several more planned.
• Own the legacy voice switch and mentor a junior engineer on the team.
• Simplified voice call routing, which improved call quality and made faults easier to diagnose.
• Retired a costly legacy circuit-switched trunk by bringing traffic in over SIP through a SIP-to-SS7 protocol converter into the legacy voice switch. Cut the monthly recurring cost from roughly $100k to $8k.
• Migrated roughly 8,000 DIDs (direct inward dial numbers) with no customer impact, including two safety-of-life services (ATS and GMDSS).
• While on the NOC floor as a Network Control Specialist 1, built a Telegraf, Prometheus, and Grafana pipeline that collects about 40 metrics per second from the MPLS network, and wrote Python tooling for verification and maintenance procedures.

• Deployed more than 60 computer-vision point-of-sale kiosks across Arizona Circle K stores.
• Trained staff at more than 20 locations on operation, basic troubleshooting, and escalation.
• Diagnosed and repaired more than 50 hardware and software faults in the field.

• Onboarded more than 250 customers onto a self-checkout system.
• Reported field issues back to the deployment team so they could be fixed quickly.

• Provided first-line hardware and software support and kept workstations patched and provisioned.
• Built a synchronized digital-signage system for idle displays and designed a mount to extend Wi-Fi coverage into a large conference room.

• Replaced the business phone service with a self-hosted SIP/VoIP system, including a mobile extension.
• Rebuilt the network to support on-site hosting, public Wi-Fi, and a CCTV system.
