At Convoy, we had a weekly retrospective for our on-call where we discussed issues that came up during our on-call shift. The engineer on duty had to look at the Slack posts generated by Pagerduty to write a summary for the retro meeting. This process could take hours depending on the volume of issues that came up during the week.

Automated the weekly on-call summary generation process using Python and Slack API. Previously, engineers took 2-3 hours writing up summaries manually. The script gathered all related threads and comments per issue which reduced writing summaries down to 20 minutes.
