During February 2026, Moura enhanced the apache/spark repository by improving the PySpark Data Source API documentation. Focusing on developer experience, Moura surfaced the DataSourceReader.pushFilters method in the Python API docs, addressing discoverability issues and reducing onboarding friction. The work involved updating Sphinx-based documentation tooling, verifying changes through local builds, and ensuring seamless navigation within the API reference. Moura’s contribution required proficiency in Python, API development, and documentation workflows, with careful attention to aligning documentation with implementation. Although the change was documentation-only, it demonstrated depth in technical writing, build verification, and effective cross-team collaboration to improve the project’s usability.
