Over a two-month period, contributed to the powsybl/pypowsybl and powsybl/powsybl-entsoe repositories by delivering targeted feature enhancements and maintenance. Enhanced the Rao results export in pypowsybl by upgrading the OpenRao library, introducing configurable JSON output, and supporting flows in both amperes and megawatts, all implemented using Java and Python with a focus on robust API integration and unit testing. In powsybl-entsoe, completed a dependency upgrade cycle, updating core components to the latest versions while maintaining API compatibility and validating changes through continuous integration. The work emphasized stability, future-proofing, and improved test coverage without introducing breaking changes.
