Developed comprehensive architecture documentation for the Baselibs component within the qorix-group/score repository, focusing on establishing a scalable foundation for onboarding and long-term maintenance. The work detailed module overviews, core utility libraries, threading, data processing, file system operations, memory management, and OS abstraction, all articulated using RST and software architecture best practices. By providing a static architecture view and clear rationale for architectural decisions, the documentation aimed to streamline cross-team collaboration and reduce onboarding time. This effort emphasized clarity and consistency, ensuring that future development and maintenance activities could proceed efficiently with well-defined technical guidelines and supporting documentation.
