Buy Roman a coffee


Hey 👋 !

Over the years, I learned the hard way that managing an investment portfolio somewhat scientifically (for geeks, think modern portfolio theory) requires some strong knowledge in mathematics and in computer programming.

For DIY investors who already need to do everything by themselves (gathering information on the assets hold in their portfolios, managing buy and sell orders...), this can be far too much to bear.

With this in mind, I'm developing Portfolio Optimizer so that the personal investors who simply need to use computational tools to manage their portfolios can do so without dedicating years of their life to study advanced mathematics and computer science, or hiring an army of PhDs.

All coffees are welcome !
