WHO MAKES THIS

Hi, I'm Elijah. I've lived in Portugal for five years (still waiting on the passport) and along the way I built little tools for myself: a NIF checker, an IRS calculator, a way to make sense of the paperwork. They saved me hours, so I cleaned them up and put them here. Free, no login, and every number is checked against the official sources.
