and organized by

Infopro Digital Trade Shows

Program committee

Led by Systematic Paris Region, the program committee is made up of Open Source experts. Their role is to define the conference content orientation by suggesting relevant and impactful themes, subjects and speakers. The program committee members will also be responsible for promoting the call for proposal within the Open Source ecosystem and will evaluate the resulting proposals.


In a world where digital technology is becoming more and more prevalent, there is one area where growth is even more pronounced than any other: Open Source.
The reason is simple: these open technologies are the perfect answer to the new challenges of sovereignty, sustainability and transparency that are driving states, communities and companies concerned about the protection of their data.
For the third edition of this unmissable European event, we have decided to focus on IT security. Every day, in this sector, the news shows us that Open Source provides multiple answers to the difficulties linked to cybersecurity, encountered in all sectors of activity.
The most qualified people will be speaking on their favourite topics: setting up an Open Source policy and legal issues, sustainable digital, technologies (web, cloud, infrastructure, languages), connected objects and open hardware, communication and business applications, artificial intelligence and data management.

Joins us and share the Open Source experience!

Customer Success Engineer & Customer Success Manager


I started development and geeking so long ago that I’m not sure of the date (it’s been at least 40 years), but I remember a machine: a TI57 (for the youngest of you, it was a programmable calculator from Texas Instrument). From the beginning it was a passion, and my luck was that I was able to make it my job (for someone who didn’t want to work, being able to turn his hobby into a job was unexpected). Since then, I have worked in various professions, always related to “tech” and I continue to learn every day by contributing to open source projects (in various ways: code, presentations, hands-on-lab, training…).


Consultant and Research Practitioner
