There's a big difference between being a developer and being somebody with a CS degree. In my experience with hiring developers, I always value people being self-taught. This means you made things work!

To me, that's the difference between a developer and a programmer. A programmer might write technically better code, but often gets stuck when something does not work as intended as is often the case in web browsers. A developer will find a way to make it work, and make it work well for the user.

So don't sell yourself short and keep on learning. You may in fact be more desirable than somebody with a CS degree.
