I am a professional Bicycle Mechanic. I have a degree as an Electronics Engineer, but haven't found a good application for that at the moment.
I build bikes, fix bikes, sell bikes, fix fitness machines, shovel snow, sweep floors, hang pictures, paint, answer phones, manufacture parts, clean the bathroom, and install lighting...and that's just at the bike shop!
With enough time and money, I can fix anything (or at least, that's what I keep telling the boss).
I've some welding experience, a little machining, a good deal of carpentry (especially CNC cabinetmaking), engine repair, construction/remodeling, concrete, extensive computer and electronics troubleshooting/repair, radio communications...
I'm a Jack Of All Trades kinda guy.
