Worked on the cctbx/cctbx_project repository to streamline the packaging process for the xfel module by removing its direct dependency on simtbx, thereby enabling conda packaging and improving distribution readiness. Used Python to refactor the codebase, relocating the outlier detection function to a local utility module and introducing conditional imports for the diffBragg PHIL scope. Focused on code refactoring, dependency management, and package development to reduce the external dependency footprint and enhance build reproducibility. These changes positioned cctbx.xfel for easier downstream deployment and maintenance, resulting in a more robust and manageable build pipeline for future development.
