Worked on the lsst-ts/ts_wep repository to deliver five new features over two months, focusing on backend performance and workflow efficiency. Introduced cross-component caching and lazy initialization using Python, which reduced runtime overhead and improved memory usage for telescope pipeline components. Refactored instrument model and mask preparation by caching Zernike basis computations and adopting a GQ-based calculation, accelerating the TIE algorithm and mask generation. Enhanced test reliability through improved metadata comparison and data handling, and updated documentation to reflect these optimizations. Demonstrated skills in algorithm optimization, scientific computing, and code refactoring, resulting in faster, more scalable production workflows without bug regressions.
