Catalina Yepes focused on enhancing documentation quality in the gem/oq-engine repository, delivering two feature updates over two months. She improved the Exposure Model Inputs documentation by introducing a new 'exposureFields' section, refining explanations for conversions and occupancy periods, and updating XML examples to align with current practices. In a later phase, Catalina clarified taxonomy mapping documentation, correcting table formatting and header semantics to accurately reflect risk_id mappings. Her work, primarily using RST and XML, emphasized technical writing and documentation skills, reducing onboarding time and misconfiguration risk. The updates improved maintainability and ensured documentation remained consistent with evolving code references.
