Being a developer was the next step of being a Computer Engineer.
But why did I became a Computer Engineer?
Code is my prosthetic extension. There are things I can't do, or are too tedious for me to do. But when code written by me performs some task X, I get the feeling that I'm capable to perform the said task X, which is a great feeling.
And I think that's why I'm a developer in the first place and will continue to be so.
