Big fan of Tiller.
In my work life I am a commercial estimator for a national contracting company. This is where my grounding came with spreadsheets and even created my own estimating workbook that has increased speed and accuracy. Switched to google sheets a few years ago, never looked back. The challenge of coding is a struggle, but my spare time is spent learning. Additionally created equity analysis tool and tracking workbook that has been quite fun to build.

Have a wonderful life with my wife and 3 dogs.
Cubs fan …with a tattoo to prove it
