We promote the free sharing of knowledge and collaborative learning in a friendly, respectful environment. To do that, we run workshops, talks, training sessions, learning guides and open projects that connect beginners with professionals.
We believe in ethics, curiosity and getting things done: we share best practices, applied research and useful tools for cybersecurity, QA/testing, development, automation and innovation. Every week there are activities to learn, take part and contribute.

The biggest tech event in the Cuyo region. Once a year the whole community meets in person: companies, education, communities, prizes, games and live streaming, all in a single day with free admission.
More than 40 tech companies and 20 educational institutions under one roof, so you can discover where to study IT, see what the industry is working on and drop off your résumé at the booths you like most. And if you can't make it, it's streamed live.
