Worked on the OpenFUSIONToolkit/JPEC repository to deliver end-to-end integration of IMAS and IMASdd within the GPEC framework, enabling seamless reading and writing of equilibrium data and stability results. Leveraged Julia for scientific computing and numerical methods, introducing new APIs and data flows to support COCOS convention handling and multi-n_tor routing with accurate eigenvalue association. Developed comprehensive unit tests and a benchmark example to validate interoperability between IMASdd and g-file workflows. Modernized the CI stack and updated documentation to align with IMASdd 8.x and Julia 1.11+, ensuring robust, maintainable support for evolving data analysis requirements.
