I have been working as a programmer since the late '90s, and as a freelancer, off and on, for much of that time.
My homepage usually indicates when I'm next available, but when I am, I can do short- or long-term contracts, with fixed price, hourly billing, or weekly billing.
I have been employed on contract for code reviews, greenfield development, bug hunting, et cetera, in almost any language you can imagine, at any level from the bare metal on up.
Drop me a line at [email protected] to discuss rates and availability. A discount is available for free/open source software work.
