Jess contributed to the apache/sedona-db repository, building out advanced geospatial and raster analytics features over seven months. She developed core modules for coordinate reference system (CRS) transformation, multidimensional WKB serialization, and robust raster data handling, leveraging Rust, C++, and Apache Arrow. Her work included implementing UDFs for CRS management, raster-to-world coordinate conversion, and affine transformations, as well as optimizing CRS deserialization for performance. Jess focused on schema design, API clarity, and comprehensive testing, ensuring cross-database compatibility and maintainability. These contributions enabled richer spatial analytics, improved data interoperability, and laid a strong foundation for future geospatial data processing enhancements.

Dec 1, 2025December 2025 — Apache Sedona DB: Delivered a raster/CRS feature set and performance improvements, enabling richer geospatial analytics and faster data ingestion. Key deliverables: - RS_RasterToWorldCoord UDFs: raster pixel to geographic coordinate conversion (two commits: a3dcc12365ac10ad52ab8f79c57159cffb42991a; 6c862162b872abef3f4c2317d5bf67528e4389a7). - RS_WorldToRasterCoord variants: world-to-raster coordinate conversion with updated registrations and benchmarks (commit: 257bc8fb3c4e5b8a12dad4d7bc976fa3af2cedc8). - RS_Rotation UDF: raster rotation by a uniform angle in radians (commit: 45b3162c38515f918909f24f8054bf6c05c91201). - RS_Envelope Raster Bounding Box: computes raster bounding box as a WKB Polygon, with tests and documentation (commit: 61387a168f73e1e5fd6df498d9fbb896d9608f79). - CRS Deserialization Performance Optimization: optimize input handling and caching in deserialize_crs() to cut overhead (commit: ea4ed976121c4c823cd130cf6ffe569461bd6ea8). Impact: - Enables end-to-end raster analytics and improved spatial indexing; faster CRS loading reduces ingestion and query latency, boosting overall throughput for large rasters. Technologies/skills demonstrated: - Rust-based UDF development, performance benchmarking, testing and documentation. - Performance optimization and caching strategies for CRS deserialization. - Spatial data modeling and WKB polygon handling.

Sep 1, 2025September 2025 (apache/sedona-db) monthly summary focusing on key accomplishments, major features delivered, and business value. Key features delivered: - CRS and SRID management enhancements: Introduced and improved CRS/SRID capabilities including ST_SRID retrieval, ST_CRS retrieval, ST_SetCrs setting, ST_SetSrid (unsetting with 0), and enhanced CRS handling in ST_Transform. Included tests and EPSG:4326 SRID handling fixes. - ST_FlipCoordinates Utility: Added ST_FlipCoordinates to swap X and Y coordinates across geometry types with cross-database compatibility and tests. - Sedona Schema Argument Matching Enhancements: Added an 'or' argument matcher, standardized optional argument matching, and expanded tests for argument validation. - API Renames and PROJ Logging: Introduced PROJ logging level configuration; renamed 'collect' to 'to_memtable' and updated documentation/notebooks to reflect API changes. Major bugs fixed: - Fixed missing SRID on EPSG:4326 (EPSG:4326 SRID retrieval) to ensure accurate spatial queries and data joins. - Accept SRIDs as args to ST_Transform (#62) resolving inconsistency in transforms across SRID configurations. - Added unset behavior for ST_SetSrid (0) to clear SRID cleanly and avoid stale values. Overall impact and accomplishments: - Improved spatial accuracy and reliability of queries with robust CRS/SRID handling, broader interoperability across databases, and clearer API semantics. - Enhanced developer experience through API consistency, better observability (PROJ logging), and expanded tests reducing regressions. - Strengthened test coverage for CRS/SRID paths, coordinate transformations, and argument validation, enabling safer future refactoring. Technologies/skills demonstrated: - Geospatial functions and CRS/SRID management, coordinate transformations, and test-driven development. - Cross-database compatibility considerations and data integrity for spatial operations. - API design/renaming practices, documentation updates, and configurable logging (PROJ). - Code quality improvements, refactoring, and robust argument matching patterns.
