Worked on deployment hygiene and stability improvements for the zanfranceschi/rinha-de-backend-2025 repository, focusing on ensuring production environments consistently run the intended Docker image version. Addressed an issue where the correct image was not deployed by updating the docker-compose.yaml file to reference the latest image tag, thereby aligning deployments with release expectations. Additionally, removed obsolete log files to streamline the runtime environment, reduce disk usage, and simplify log analysis during incident diagnosis. Utilized Docker and YAML configuration skills to enhance deployment reliability and maintainability, with a focus on release hygiene and issue tracing rather than feature development during this period.
