Worked on the traefik/traefik repository to implement Docker API Version Auto-Negotiation, addressing compatibility challenges across varying Docker server versions. The solution removed hardcoded API version constants and introduced dynamic negotiation logic, allowing the backend to automatically determine the appropriate API version at runtime. This approach reduced the risk of version drift and simplified ongoing maintenance by centralizing version management. The work was delivered using Go and focused on backend and API development, ensuring smoother integration with diverse Docker environments. By enhancing maintainability and reducing brittle dependencies, the update improved the reliability of Docker deployments within the traefik/traefik project.
