Back end development is my thing.

I'm usually very fond of making continuous use of technologies I'm very experienced in, until I get blown away by a cool new thing that's gonna magically solve all my problems. From this point onwards, I just get avidly eager to research it and dominate it.

Being this way, I consider myself very knowledgeable in a small number of technologies. Sometimes this is a good thing. Other times, this is not.
