Worked on the starsimhub/starsim repository to enhance code organization and documentation, focusing on maintainability and onboarding efficiency. The main contribution involved refactoring Python code by relocating the Analyzers class to a dedicated modules.py file, promoting a more modular and extensible architecture. Documentation improvements were delivered through targeted updates to the README.md, clarifying section purposes and streamlining contributor guidance using Markdown. No major bugs were addressed during this period, but minor issues were triaged as needed. These efforts established a clearer project structure, supporting faster future feature development and reducing ramp-up time for new collaborators through improved documentation and modular design.
