About this Project

Some time ago, I picked up a habit: each time I face a mundane task I’m likely to repeat, I create a tool to make my work more efficient. This site is a collection of such tools.

Currently, there are three sections: calculators, indicators, and total returns.

If you have any ideas or encounter a bug, please reach me in X DMs.
