We started a project in January for which I was the sole developer, to automate tedious interaction with a vendor's ticketing system. We have a storage environment with about 400,000 commodity disks attached(for this vendor-- there are other vendors too), in sites around the US and Canada. With a weekly failure rate of about 0.0005%, that means about 200 disks a week need to be replaced.

This work-- hardware investigation through storage appliance frontends, internal ticket creation, external ticket creation, watching the external ticket for updates to include in our internal ticket --was all manual, and for around 200 issues a week, it was done by one guy for two years. He was hopelessly behind. This is all automated now, and this morning, I pushed this automation from dev/test to production.

It feels great to see your work helping people around you.
