Why they attended our past editions

“It was really cool to interact with such a great, international audience which was very focused on the topic at hand. The talks were amazing! I'm looking forward to the next edition.”

Tristan Nitot, Digital Commons and sustainable IT Ambassador (Octo Technology)

Green IO conference is not only for professionals of the intersection between sustainability and software engineering. It’s a space for developers, engineering leaders and business to connect and share their experiences. It’s for everyone, who want to integrate sustainable practices in their daily work, regardless in which area you are working. I am very glad to see how the community is growing and building connections that continue after the conference as well.
