Thorsten Klaes developed a CI/CD workflow and backend competition class structure for the bettercodepaul/swt2-bsa-backend repository during March 2026. He implemented GitHub Actions to automate build, test, and deployment processes, streamlining feedback and deployment reliability. Using Java and YAML, Thorsten established a configurable backend framework to support competition scenarios, focusing on scalable architecture and maintainable configuration management. His work included code quality improvements, such as removing unused variable assignments, and demonstrated skills in CI/CD automation, REST API development, and Spring Boot. The depth of his contribution lay in enabling automated workflows and a flexible backend structure for future enhancements.
