Over seven months, Joan Selga enhanced OpenNebula’s documentation and infrastructure tooling across the OpenNebula/website, OpenNebula/docs, and OpenNebula/one-apps repositories. Joan delivered features such as GPU monitoring metrics documentation, Ceph and LVM backup workflow clarifications, and a dedicated VM appliance for NVIDIA Fabric Manager, focusing on reliability and operational clarity. Using C++, Bash, and shell scripting, Joan implemented stateful automation for partition recovery and robust installation routines, reducing manual intervention and improving deployment resilience. The work demonstrated depth in technical writing, DevOps, and system administration, consistently aligning documentation and code to support onboarding, maintainability, and customer-facing release quality.
January 2026 (OpenNebula/one-apps): Delivered Fabric Manager Boot Manager with Automatic Partition Recovery, introducing stateful appliance capabilities and robust setup enhancements. Implemented automatic recovery of the last configured partitions and added state management functions to read/write active partitions for restoring the prior state after reboot or failure. Also improved the Fabric Manager installation and configuration for robustness and ease of use. Overall, this work increases system resilience, reduces manual recovery time, and enhances deployment reliability.
