Experience

    Wrote a scheduling tool for IBM's managed hosting team. It integrated with their in-house ticketing system. It was primarily used for creating tickets at scheduled times for the managed hosting team to perform patching on customers' machines. However, it was capable of creating a schedule for any purpose.
