Start writing tools for sysadmins. Think of all the times when you hit a wall because there was no inventory database that could be queried from command line, not just browsed through a web UI, or when you wanted to coordinate several backup systems but keep them separate, or when you wanted to run a well-defined script on a remote host after an event, or when you wanted to plug in your own data processing into a monitoring system, or run a command on a set of servers with some of them being temporarily down -- and later review the run reports, or maybe to keep syslog logs in some place that could be queried and not be as brittle and slow as Elasticsearch. There are still blank spots in sysadmin's tooling, but nobody looks this way. And there are still companies that know that they need tool writers.
