My whole life? Interesting question... since I was 7, so pretty much yes! (And since before I dropped out of college, I've been doing this professionally, except for one summer early on where I drove a truck around delivering hoagies to businesses!)

And certainly. A lot of projects were small enough where I did everything from set up the hosting environment and domain names, build the database, write the application and maybe even do front-end development. But I don't usually have the confidence to be the final point person on larger projects. I suspect I'm getting there. You can only stand to do things that you know won't turn out well at someone else's direction, only to soon watch them turn out poorly... so many times before you start to believe in yourself a little.
