Not really, its mostly a hobby/nerdy/because I can thing. I am a software engineer with a decade of experience. The job sometimes requires virtual sys admin work (VM/container, cloud networking, etc). Setting up my own baremetal cluster has given me more insight into how things work, especially on the network side. Most of my peers take for granted that traffic gets in or out of a cluster, but I can actually troubleshoot it or design with it in mind.
