Worked on modularizing and enhancing the HATS region search within the astronomy-commons/hats repository, focusing on refactoring search logic into a dedicated submodule for improved maintainability and extensibility. Leveraged Python and YAML to externalize and standardize spatial filtering functions, ensuring consistent region search capabilities across related projects. Expanded automated testing to validate box, cone, and polygon search accuracy, and updated developer documentation to clarify environment setup and contribution workflows. In astronomy-commons/lsdb, stabilized dependencies by pinning to the HATS main branch and modernized development tooling, supporting Python 3.11 and 3.12, which streamlined cross-repository maintenance and improved contributor onboarding.
