Meet the team behind PyCon Greece

PyCon Greece comes to life thanks to a dedicated group of volunteers, developers, designers, and community builders who believe in the power of working together. From late-night bug fixes to small ideas that grow into something bigger, we share one purpose: to make this event welcoming, inspiring, and memorable for everyone.
