Worked on the xpsi-group/xpsi repository to enhance internal code quality and maintainability, focusing on technical debt reduction rather than new feature development. The primary contribution involved removing unnecessary print statements from the CustomPhotosphere component and adding clarifying comments to the integrator function, which improved code readability and reduced console noise. These changes, implemented using Python and leveraging skills in code documentation and scientific computing, laid a foundation for future feature work by making the codebase easier to understand and modify. The improvements also support faster onboarding of new contributors and reduce the risk of regressions in upcoming development cycles.
