About 5 hours a week on https://getelapse.com, chunked into 20 minute slots like lunch breaks or downtime at home between family stuff. The only way I'm able to make forward progress is by being super strict about CI+CD.
It's actually doing a good job of forcing me to code really well, because if you've only got 20 minutes to get a thing done, you can't have much cognitive overhead or switching costs.
