I've worked on Salesforce, SharePoint, and Lotus Notes, integrating them and migrating between them. Maybe I should just specialize in all the platforms nobody else wants. (Or maybe I accidentally already did.)
Ha! That's what I've done at work. I handle the custom code integrations - a Jenkins plugin, some gradle glue, a VSCode plugin and some custom git server side hooks. Everybody loves me for taking on the undesirable things.
