During September 2025, Dermen worked on the cctbx_project repository, focusing on simplifying the packaging process for the xfel module. He removed the direct simtbx dependency, which enabled conda packaging for cctbx.xfel and improved distribution readiness. Using Python, Dermen refactored the codebase by relocating the outlier detection function to a local utility module and implemented a conditional import for the diffBragg PHIL scope, reducing runtime coupling and external dependencies. His work emphasized code refactoring and dependency management, resulting in a streamlined build pipeline and laying the foundation for easier downstream deployment and ongoing package maintenance.
