A tax platform that has come back every single year since launch.

PIT Projekt lets individuals file their annual tax return online. It handles personal financial data, it has to be correct against legislation that changes every year, and essentially all of its traffic lands inside a few weeks.

That combination — regulatory accuracy, data sensitivity, and seasonal load — is the reason this project sits in the portfolio. It is not the most visually ambitious thing we have built. It is the clearest evidence that what we build keeps running.

Each tax year brings a fresh round of rule changes, form revisions, and testing. The platform has absorbed that cycle repeatedly without a rebuild.
