You can hire me thru your company or thru the Upwork system. I have a well-established online profile which you can view here. Please note that its visible for Upwork users so you have to log-in.
I also have a GoLance account. It works the same as Upwork. You can find my GoLance profile here.
I am also available thru Guru.
