Unfortunately, when you move on to another job, your "much easier" app becomes an orphan. I have seem this happen multiple times. The hot shot developer creates his own thing because it is too much of a hassle to do in SharePoint. Then the developer moves on. And the "much easier" app slides into a slow decline and one day dies because nobody know how to fix it.
