During October 2025, Sergio Escorihuela Ruiz developed a Dockerized Sum Calculator Service for the a10pepo/EDEM_MDA2526 repository. He containerized a Python script that accepts two input numbers as parameters and returns their sum, enabling reproducible execution across different environments. By leveraging Docker and Python, Sergio established a consistent, container-based workflow that streamlines onboarding and prepares the project for continuous integration. Although the work focused on a single feature and did not address bug fixes, it laid a solid foundation for future enhancements by improving deployment readiness and developer productivity through standardized, parameterized execution of core functionality within containers.
