PROFILE
Yann Forget
Yann Forget developed and maintained core data engineering features for the BLSQ/openhexa-toolbox, focusing on climate and health data integration. Over nine months, he enhanced ERA5 data retrieval and processing by integrating asynchronous workflows and upgrading to the ECMWF datastores client, optimizing storage with Zarr and improving pipeline reliability. He expanded DHIS2 integration, enabling robust metadata extraction, multi-group data workflows, and DataFrame-centric APIs for analytics. His work involved extensive use of Python, Pandas, and API design, with careful attention to error handling, test coverage, and maintainability. The resulting codebase supports scalable, reliable data pipelines for production environments.
