Worked on enhancing the Injection Range Action Adder in the powsybl-open-rao repository, focusing on backend development and API design using Java. Developed new methods to allow network elements to be associated with or without explicit keys, increasing flexibility in how injection range actions are configured. Introduced a duplication guard to prevent the same network element from being added multiple times, thereby improving data integrity. The work emphasized clean code and robust feature delivery rather than bug fixes, resulting in a more adaptable and reliable interface for managing injection range actions within the system’s backend architecture during the development period.
