This session focuses on developing a Google Calendar add-on designed to streamline time tracking by converting informal notes, such as 'spent two hours on a slow query,' into structured calendar entries. The workshop will demonstrate how to implement this solution using either Google Apps Script for browser-based execution or as a portable Apache-2.0 licensed Go service, offering flexibility in deployment. Participants are encouraged to bring a laptop and a Gmail account to engage with the practical aspects of the build.
