My hopes and plans for the NixOS community
About me I'm excited to share that I'm running for a seat on the NixOS Steering Committee. Before diving into my motivations, I'd like to take a moment to introduce myself --- especially for those in the community I haven't had the chance to work with yet. I am 28 years old and currently based in Paris, France. I have been involved in the NixOS community for about four years, with contributions spanning technical, organizational, and academic domains: Technical work: I am a committer to nixpkgs, where I contribute to maintaining the systemd-boot backend; I am also the author of a port of the Proxmox hypervisor on NixOS. Community involvement: I have helped organize NixCon 2022, participated in the coordination the NixOS devroom at FOSDEM in 2023 and 2024, and organized the Paris NixOS meetup; Academic research: In the context of my PhD, I study the impact of functional package management on the software supply chain and explore possible avenues for improvement.
