Founder & Developer · Active investor since 2018

I created Podatek Giełdy out of personal frustration. Existing tools were inaccurate, didn't support foreign brokers, or required manually entering hundreds of transactions. After spending hours in Excel and making several tax filing errors, I decided to build what I needed myself — and make it available to other investors.
