During March 2025, contributed to the PTB-MR/mrpro repository by focusing on stability and maintainability through targeted dependency management and code refactoring. Updated the pydicom dependency to version 3.0.1, ensuring ongoing compatibility and security for the project. Refactored core numerical computing components, specifically ProximableFunctional and LinearOperator, to enforce immutability and prevent side effects by clamping non-negative sigma values and removing in-place additions from operator norm calculations. These changes improved code clarity and reliability, supporting future feature development. Work was implemented using Python and TOML, leveraging skills in dependency management, numerical computing, and operator theory to enhance production readiness.
