I'd be very interested to hear less about the process, and more about the app itself.
If a week "in the hole" resulted in a Slackbot that greets people when they enter a Slack channel, I'd be significantly less impressed than if you'd built, say, a CI pipeline, or something that automatically creates Jira tickets based on outages, or automatically handles subscription renewals or something.
Plus, the number of commits & PRs is absolutely not a useful metric. How well is the app running? How many bugs are you finding day to day? How much functionality is missing, how easy is it to add new functionality based on user feedback, etc? Monitoring?
