While I know nothing about you and your skills, this doesn't have to be always that simple. People who are "the only developer" in a company often get detached from the developer community, living in a kind of technology bubble they created. These people always solve the problems "their way", often obsolete, using inferior tools. They can write tons of code, when there's already a tool which does the trick just a google away. Again, I am not talking with you personally in mind, but simply being the sole programmer doesn't make one indispensable.
