Jordão Bragantini developed and enhanced data interoperability features for the live-image-tracking-tools/geff repository, focusing on backend extensibility and robust data conversion workflows. He implemented a modular GEFF writer helper and refactored core write paths to support alternative backends, including a Rustworkx integration for efficient graph processing. Using Python and Cython, Jordão introduced CLI and Python modules to convert legacy CTC data to GEFF, and built utilities for exporting GEFF structures to pandas DataFrames and CSVs. He stabilized Zarr-based array writing across versions, expanded parameterized testing, and updated dependencies, demonstrating depth in backend development, data engineering, and scientific computing.
In September 2025, focused on feature delivery for GEFF: introduced Data Conversion Utilities to convert GEFF data structures into pandas DataFrames and CSVs, with new CLI commands and Python APIs, plus dependency updates and a robust test suite. No major bugs were fixed this month; improvements centered on robustness and usability to enable downstream analytics.

August 2025: Stabilized the Zarr-based write path in live-image-tracking-tools/geff, delivering a cross-version compatibility fix and expanded test coverage. Key outcomes include ensuring zarr_format is correctly passed to write_id_arrays for Zarr v3, and adding parameterized tests for v2 and v3 to prevent regressions. This reduces data-write errors, improves reliability of image-tracking data pipelines, and reinforces maintainability through better test coverage and traceable commits.

July 2025 focused on expanding GEFF backend extensibility and data interoperability. Key features delivered include a modular GEFF writer helper and refactor of write_nx to use the helper, a new data conversion path from CTC to GEFF via CLI and Python modules, and a Rust-backed backend (rustworkx) with read_rx/write_rx support. These efforts improve backend modularity, data interoperability, and testing coverage, reduce future integration risk when adding new backends, and enable end-to-end data workflows from legacy formats to GEFF.
