Fabio Luchetti

Fabio began his journey with the ATLAS Distributed Computing group in 2021. Progressively taking the lead of Operations within the Distributed Data Management team, his contributions to Rucio focus on the storage consistency-checks component and integration efforts. Prior experiences include the development of the Kubernetes CI/CD framework, the client-server protobuf integration and the release-cycle workflow of tagged releases for the EOS storage service at CERN.

Francesc Torradeflot

Francesc holds a degree in Mathematics and works as a Software Engineer at PIC since 2016. After some years of full-time commitment to ESA's Euclid mission, he gradually shifted his duties to the development and maintenance of common tools for data analysis. Given the importance of jupyterlab and Rucio in PIC's services portfolio, contributing to the rucio-juptyerlab extension was a logical step.

Dimitris, a PhD candidate in computer science at the University of Bern and MSc geomatics engineer from TU Delft, joined CERN in June 2024 to enhance Rucio. As part of the DaFab AI project, Dimitris will extend Rucio’s capabilities to support Earth Observation data, marking its expansion beyond high-energy physics data. This entails new metadata capabilities for Rucio along with enhanced discovery mechanisms. In this role, Dimitris becomes a lead deputy for the Metadata component and lead for Rucio's Database. In his spare time, you might find Dimitri exploring new horizons on his motorcycle.
