Worked on the OpenwaterHealth/OpenLIFU-python repository to deliver comprehensive architecture documentation, focusing on clarifying module boundaries and the end-to-end treatment workflow. Using Python and technical writing skills, created a detailed architecture.rst file and an accompanying SVG diagram that map out the system’s ten modules, class hierarchies, and design patterns. This documentation enhanced cross-team alignment and improved onboarding by making data flow and dependencies explicit. The approach prioritized maintainability and future readiness, enabling safer refactoring and more efficient QA planning. No bug fixes were addressed during this period, as the primary focus remained on architectural documentation and knowledge transfer.
