Worked on the zanfranceschi/rinha-de-backend-2025 backend project, delivering a new submission workflow that streamlined how entries are submitted and processed within the system. Focused on improving development and testing environments by refining Docker Compose configurations, which enhanced stability for both local and CI pipelines. Addressed reliability issues by stabilizing CI reruns and mitigating flaky tests, resulting in more predictable deployments and safer releases. Grouped rerun-related commits to support efficient batch processing and ancillary actions. The work leveraged Go and JavaScript for backend logic, with Docker and Kubernetes used for containerization and orchestration, emphasizing performance tuning and configuration management.
