Mostly in the USA
Freelance Lighting Designer, Master Electrician, and Automation Technician (Lighting and motion control). I'm one of the many who keep everything going for the theatre or music show, corporate event, TV show, or Sports event you're seeing.
I am one of those known as Roadies (we actually hate that word), stagehands, techs, entertainment professionals, or a myriad other names.
I design lights, lay out power for large scale events, design, program and implement automated scenery, trussing, and other equipment, rig up and down, build very large scale outdoor stages, and fix just about anything that gets broken.
