Worked on refining simulation parameters for the Altona Altstadt area within the MARS-Group-HAW/model-soh repository, focusing on configuration-driven model tuning. Leveraged configuration management skills to centralize and update region-specific parameters in a single JSON file, improving both simulation fidelity and long-term maintainability. No user-facing features were released during this period, as the primary goal was to enhance the underlying model’s accuracy and stability. This approach established a foundation for rapid parameter experimentation and streamlined future feature development. The work emphasized careful structuring of configuration files and precise parameter adjustments, utilizing JSON and configuration management best practices throughout the process.
