They also needed someone capable of producing customer quality code to release with their software. My mandate on the development side was to help make the software operational for the customers, and productise it in such a way that it was palatable by customer operations staff.On the systems side I setup the infrastructure almost from scratch, installing and configuring systems, storage and networks as appropriate.This was a very nice opportunity for a systems person, the chance to do it right from the beginning.
