Check Slack, and my google calendar for the day.
Open up asana, check our priority queue and ensure my in progress/upcoming are set accurately (remote team, so this is very important)
I work mostly with data scientists. So, some days it's pure cowboy coding. Experimental and research stuff. Lots of image processing, NLP, and API design stuff.
After I finish the first task of the day, contact the Chief Scientist/senior data scientists. Review, consult, plan if we can do more to it or if its worth 'graduating' to a larger product.
Or, if its a larger, production project consult with product and VP of eng as well. Ensure all delivery needs are met.
At the end of the day we have an informal chat of no specified amount of time. The 'end' of the day is often midnight-1am-ish for us because we have people in 5 time zones. We try to be as flexible as possible especially with a guy in South Korea.
