PROFILE
Julian Tölle
Worked on maintaining cloud infrastructure compatibility by updating Hetzner server instance types across the flatcar/mantle and flatcar/scripts repositories. Addressed upcoming deprecations by implementing a new default server type in flatcar/mantle and upgrading from cpx11 to cpx22 in flatcar/scripts, ensuring stable deployments and reducing risk of service disruption. Coordinated changes across repositories to align with Hetzner’s changelogs and maintain downstream consistency. Utilized Go and Shell scripting to manage infrastructure as code, demonstrating skills in API integration, DevOps, and backend development. The work focused on proactive change management to ensure reliable, future-proof cloud environments through January 2026.
