I am currently employed as a Senior Network Engineer for a midsize enterprise in the healthcare industry. I started out in SMB networking and have been working on enterprise networks for nearly five years. In the past five years, I have gained an enormous amount of practical knowledge and experience.
Ivan Pepelnjak wrote an excellent piece “On I-Shaped and T-Shaped Skills” which highly influenced the things I have decided to focus on. I enjoy “routing and switching” which is why I worked to obtain skills to the expert level in that area. Yet, I am constantly learning and rounding out my skillset in other areas as well, such as the fundamentals of automation, wireless, datacenter technologies, and more.
The computer network represents the arteries of the modern business environment, with the data flowing across as the lifeblood. By having expert level networking knowledge, and fundamental knowledge of what interacts with the network as a whole, I am in a better position to help an organization thrive on produced and consumed data.
I passed the Cisco CCIE Routing & Switching written exam, and later attempted the lab exam. I gained many skills that go far above and beyond the CCNP level, including multicast, QoS, and MPLS experience (both enterprise and service provider sides).
As part of my study, I released to the public some of the study materials I had created for myself, including a deep, detailed mind-map, a collection of documentation links based on topics, and a collection of nearly 3500 flash cards.
I designed and integrated a VeloCloud-based SD-WAN environment to migrate away from a 350-site MPLS L3VPN WAN. This included a 15-site trial/PoC environment from one provider, and eventually a full production rollout using a different provider. During the migration phase, there were at one point two separate MPLS L3VPNs, two separate SD-WAN environments, two datacenters, and 350 sites supported simultaneously. I used BGP at the datacenters and various kinds of filtering and BGP policy adjustments to harmoniously stitch all of the environments together for full connectivity between all sites.
I designed and implemented the network portion of an enterprise disaster recovery plan (similar to but slightly more complex than my post Easy Disaster Recovery Plan)
I participated in the networking aspects of moving an in-house datacenter to a colocation facility, and detailed the aspects of maintaining connectivity between the old and new datacenters during the migration and lessons learned during the process.
Using Python, YAML, Jinja2 and multithreading to rapidly generate and push configurations to multiple devices.
I needed a simple configuration backup system for the hundreds of Cisco routers and switches on my network. I initially used RANCID, but then learned how to use Oxidized.
