Developed core spatial analytics capabilities in the apache/doris repository by implementing SQL spatial functions such as ST_Intersects, ST_Disjoint, and ST_Touches using C++ and SQL. Extended geometric types and integrated new methods into the function factory, enabling advanced location-based queries directly within the database and reducing reliance on external GIS tools. Complemented this engineering work by authoring comprehensive bilingual documentation in apache/doris-website, detailing syntax, parameters, and usage examples in both English and Chinese. Demonstrated skills in database development, technical writing, and spatial analysis, delivering features that improve usability, onboarding, and adoption of spatial SQL functions for end users.

Apr 1, 2025April 2025: Delivered core SQL spatial function support in apache/doris, enabling practical spatial analytics in SQL workloads. Implemented ST_Intersects, ST_Disjoint, and ST_Touches, added new methods on geometric types, and integrated them into the function factory. This work expands Doris' spatial query capabilities, enabling customers to perform advanced location-based analytics directly in SQL and laying groundwork for further GIS features. Related commit 08da6a76ec6a0979f804274c2a321b5e462d20ee ([Enhancement] Support some spatial functions (#48695)).
