Guilherme Kuhn developed a Reservations Service integration for the pucrs-constrsw-2025-2/base repository, focusing on deployment reliability and production readiness. He used Docker and DevOps practices to define the service in docker-compose, specifying build context, image, environment variables, network, and port mappings. By establishing dependencies on PostgreSQL, Keycloak, and OAuth, he ensured correct startup sequencing and secure initialization of the workflow. Guilherme also implemented a startup health check in YAML to detect misconfigurations early and enforce proper service order. This work enabled reproducible deployments and improved the maintainability of the base repository’s service orchestration within a one-month period.
