Linux Systems Administrator and Support

I'm an IT generalist with a penchant for Linux Systems Administration. Some folks call me an old school 'SysOp' since I prefer on-prem to cloud based stuff. I've done a little bit of everything from Sysadmin to Support Engineering to Break/Fix technical support. I've recently gotten into 'vintage computing' which has given me a renewed interest in working with legacy systems in particular professionally. Ideal role would preferably be an SMB shop where I can help make an immediate difference for employees and push the technology stack in use forward.
