I spent the first couple of years at my first job like this. Without going through much detail, back in 2006 I had to pull raw network performance data from some 7 elements every hour, then use a tool to convert to CSVs, then load into Excel, perform preliminary analysis, then email the Excel files to another team along with any alarming conclusions if any.

A few weeks into the job I completely automated these in python and all I had to do was turn my laptop on in the morning, then off in the evening, and I was done.
