You’d have to specify which one.
I do a variety of tech things. Today alone, I worked for three different employers - myself, editing two different concerts I shot. I chose that one, and it pretty much is a self-invented job, being a one-man, seven camera, concert video shooter. Earlier in the day, I was installing a flat screen on a wall and authoring a DVD for an art gallery. After that, I was the photographer for an estate sale company, and updating their web site. The last two are things that have just turned up. In between, I consulted on setting frequency ranges for wireless microphones for a web streaming company, and talking two other clients through computer problems, one on Mac, one on Windows.
I sometimes describe my career as a business model for ADHD.
