Worked on the single-cell-data/TileDB-SOMA repository, delivering features and maintenance across API development, documentation, and testing. Enhanced the API by clarifying DataFrame update workflows and integrating Carrara support for TileDB v3, improving data model reliability and lifecycle handling. Improved documentation quality by overhauling tutorials, deprecating outdated APIs, and refining function docstrings to support user onboarding and reduce support needs. Strengthened test infrastructure with memory-efficient fixtures and expanded coverage for error handling and data validation. Utilized Python, C++, and R to implement robust build scripting, dependency management, and cloud integration, ensuring maintainable, scalable workflows for large-scale single-cell data analysis.

Dec 1, 2025December 2025 – TileDB-SOMA: Implemented a NotImplementedError pathway for the batch_size parameter across multiple DataFrame classes, accompanied by documentation and test updates to clearly signal that this feature is not yet implemented. This work establishes a safe, explicit API behavior and provides a clear foundation for future work, reducing user confusion and support overhead.

Oct 1, 2025In Oct 2025, the TileDB-SOMA work for single-cell-data focused on stabilizing the API surface, improving developer experience, and boosting build reliability. Key outcomes include a comprehensive documentation overhaul and API deprecation (deprecating tiledbsoma.io.create_from_matrix), tutorial and community resource updates, and README guidance pointing users to TileDB Academy and the TileDB forum. A build-system reliability fix was implemented by quoting @cmake@ to prevent word splitting, improving CI stability. Additional docstring clarifications for core APIs (update_obs/update_var) enhanced developer guidance. Collectively, these changes reduce onboarding time, minimize confusion around deprecated APIs, and support smoother adoption of TileDB-SOMA. Technologies demonstrated include documentation engineering, release engineering, Python docstring maintenance, and build-script hardening.
