I've fallen into the role of SharePoint administrator at my work. I've been learning SharePoint design by help pages for the last 2 years, and now am branching out to do the same with PowerApps and Flow. My workplace has been very reliant on Excel and hard servers, so it has been quite a journey to get them into the cloud and using SharePoint. Now users (and my managers) are seeing the potential for Apps to access and display data.
