Summary
🤩
Rockstar🎓
Top SchoolSahid Ferdjaoui is a Senior Software Engineer with 17 years of experience building and optimizing cloud and networking systems from Paris. He has a strong track record in OpenStack (Neutron, Nova) and eBPF-based networking (notably contributions to Cilium), where he focused on performance, reliability, and maintainability of core datapath and migration code. As author/maintainer of Rust libvirt bindings and an active contributor at companies like Red Hat, Canonical, Juniper and Société Générale, he bridges systems-level engineering with pragmatic tooling for operators. His work often reduces operational friction—examples include disk resize optimizations, live-migration fixes, and formatting improvements that make CLI outputs human-friendly. Comfortable across C, Python, Rust and BPF, he brings deep expertise in virtualization, networking and open-source collaboration. Colleagues value his ability to refactor complex modules into simpler, better-documented components that withstand production scale.

Contributions summary:Sahid primarily contributed to the OpenStack Compute (Nova) project, focusing on optimizing XenAPI-based resize operations. Their work improved disk resizing performance by reducing resize2fs operations and implementing a VDI clone strategy. The user also introduced a "PREPARED" state for baremetal deployments, improving visibility of deployment progress. Furthermore, they added a new utility method to handle hash string generation.

OpenStack Compute (Nova) Client. Mirror of code maintained at opendev.org.
Role in this project:Back-end Developer
Back-end DeveloperContributions:8 commits in 11 months
Contributions summary:Sahid primarily contributed to improving the `nova aggregate-details` command within the OpenStack Compute client. Their changes involved making the output more human-readable by formatting data using `pretty_choice_dict` and `pretty_choice_list`. They also added tests for aggregate functionality, ensuring the v3 shell behaved similarly to v1. The user further refactored the `boot` command to utilize an existing printing function.
