Experience

1. Senior Network Engineer

   Bam Broadband Colorado

   Nov 2024 — Present · Centennial, CO, US

   Building out Juniper based MX/ACX EDGE, Core, and Aggregation network terminating WISP and GPON network serving Colorado and Arizona Residential customers. BAM being in a startup stage we have a ton of ground yet to cover. We have our sights on building out our greenfield NOKIA SRX based network supporting SRV6 core. Looking forward to our deployment deepfield defender for world class ddos tracking and mitigation. It is exciting times here at BAM. I have recently completed a full migration of the wisp mikrotik network / Juniper core over to OSPF NSSA\'s with redistribution into the ISIS Juniper core. Eliminating ospf from our Juniper core. I have developed full ISIS, LDP, MPLS standards for deployment. I completed a full rewrite of our iBGP and eBGP policies to get to a more scalable approach using best practice traffic management techniques and ISP grade peering and transit standards. Routing oncall and support as always. Still troubleshooting complex networking issues, I continue to grow and sharpen my skills on a daily basis. Building world class networks is fun!
