Work History

October 2025

1 Commits • 1 Features

Oct 1, 2025

In October 2025, delivered a major API enhancement for the genestack/openapi repository by introducing the cellQuery parameter to the omics/cells endpoint, enabling metadata-based filtering with key-value pairs, value sets, range filters, substring search, and logical operators. This improves API usability and analytics-ready data retrieval for downstream apps. The work is tracked under ODM-11755 (#469). No major bugs fixed this month for this repo. Key outcomes include updated OpenAPI spec, improved developer experience, and groundwork for future query capabilities that enable more precise cell-level querying and faster insights for analytics teams.

In January 2025, delivered API simplifications and deprecation-driven improvements across genestack/openapi and genestack/sdk, focusing on unifying how the import source is determined, reducing the configuration surface, and laying groundwork for future removal. Key changes include removing the 'source' parameter from file import request schemas with a deprecation warning and auto-extraction of the source from the link, plus deprecating and auto-extracting in the ODM data import script and removing Arvados from supported ETL sources. These changes streamline imports, reduce developer and user friction, and improve maintainability and consistency across repos.
