Working only between 8 to 10 pomodoros in average per day. That helped me to create a boundary for my workday which allows me to be more productive and feel less stressed: https://medium.com/@marcochvez/how-i-get-my-workday-done-in-...
In case you're open to suggestions, being able to adjust the Pomodoro duration would be awesome. The traditional 25 minutes always seemed a little too short for me.
And just curious about the stack if you care to share.
