During November 2025, Santiago Guzmán enhanced the mne-python repository by implementing file-like object support for reading EDF, BDF, and GDF files. This feature, developed using Python and leveraging skills in data processing and file handling, allows users to ingest data directly from in-memory streams or other file-like sources, improving integration with modern data pipelines and facilitating unit testing. Santiago preserved existing API compatibility while extending the core IO capabilities, reducing friction in data preparation and analytics workflows. The work demonstrated a focused, well-scoped engineering approach, laying a foundation for broader file-like IO support in future development efforts.
