My expense reports and timesheets.

The three shittiest parts of my job every week are:

- Approving timesheets

- Entering in my timesheets

- Entering in my expense reports

I've written a script that goes in using a phantom.js script, and automates the submission of my timesheet on Friday afternoon at 3:00 +/- 15minutes. It now takes into account travel time, Holidays, and approving time if I have time approvals due.

Same holds true for submitting expense reports in Oracle. I upload the receipt to Expensify, and as long as it's tagged properly in Expensify, it'll automatically generate the correct expense report in Oracle for the proper project based on the receipts in Expensify. This saves me, on average, about 6 hours a month.
