Summary
🤩
Rockstar🎓
Top SchoolAlexandru Cheltuitor is a Linux software engineer with eight years of hands-on experience designing robust, component-based applications and maintaining cross-distribution packages. At Proton he evolved from prototyping CLIs and packaging to architecting a modular app focused on testing, quality, and portability across GNU/Linux ecosystems. He pairs systems-level skills—systemd, dbus, NetworkManager/OpenVPN, GTK—with pragmatic engineering practices like code review and Lean-driven process improvements. A communicative, pedagogical teammate, he often takes initiative to streamline workflows (once cutting a manual inventory process by over a third) and mentors colleagues through clear, persistent problem solving. Based in Portugal, he spends free time coding and exploring information systems and data science, bringing both product-minded thinking and operational rigor to privacy-focused software. Notably, his background spans packaging and distro maintenance (Fedora, AUR) as well as shipping both CLI and GUI clients for security-sensitive applications.
