Worked on the sfbrigade/datasci-earthquake repository to enhance the reliability and maintainability of GeoJSON data workflows. Focused on backend development using Python, the work included optimizing GeoJSON data structure creation with type hinting to improve code clarity and reduce runtime errors. Introduced a pre-write validation step for GeoJSON data, ensuring only valid structures are persisted and adding robust error handling to prevent malformed files. Updated tests to use valid GeoJSON mocks, aligning them with new validation requirements. These efforts strengthened data integrity and streamlined analytic workflows, emphasizing data processing, validation, and maintainable testing practices throughout the development process.

Dec 1, 2025December 2025: Delivered GeoJSON Data Validation on Write for sfbrigade/datasci-earthquake, introducing a pre-write validation step to ensure only valid GeoJSON structures are persisted, with robust error handling and updated tests. Addressed a write-path bug to prevent invalid data from being written (commit b70297868a02881713cd8cbdf926a071358d83cf). Tests were updated to use valid GeoJSON mocks to reflect validation requirements and ensure realistic test coverage. This work reduces downstream failures and improves data integrity for earthquake-related datasets.
