Worked on enhancing plasma profile calculation reliability within the MITIM-fusion repository, focusing on improving diagnostic accuracy and reproducibility for experimental data. Refactored the eped_profiler function in Python by reordering arguments to ensure Ti_over_Te precedes netop_20, which improved calculation consistency. Introduced instrumentation by adding logging to monitor deviations in the Ti/Te ratio, enabling faster quality assurance and better traceability of plasma profile outputs. Applied data analysis and plasma physics expertise to prepare the codebase for stable production use, emphasizing business value through more reliable diagnostics and streamlined QA processes. Maintained disciplined version control throughout the development process.
