Create a virtual printer/windows service that given a print command, converts the print stream to pdf or image, and sends it to a remote JSON webservice.
Sergey always looked to understand our requirements, and showed proficient skills in the delivery of the tasks requested.
From the beginning he asked a lot of questions being sure he could deliver what we wanted for, so it made us comfortable with this contract.
He is very independent, as would be expected, and I believe he can still evolve on the pro-activity and suggesting new features.
It was a pleasure to work with Sergey, and we shall recommend him for this kind of tasks to anyone who needs it, but as I said, he proofs himself by the work already accomplished, as by the questions he asks before contracting.
