PROFILE

Macdara Ó Murchú

Over a three-month period, contributed to multiple open source projects by building robust GeoJSON Area of Interest parsing for hotosm/drone-tm, using Elixir and PostGIS to support all GeoJSON formats and improve downstream processing reliability. Addressed log clarity in astropy/astropy by refining the CCDData reader’s logging behavior, ensuring that redundant messages were suppressed when units matched, with changes validated through targeted unit tests in Python. Enhanced user experience in OpenFn/lightning by implementing a client-side tooltip feedback loop for copy token actions using Phoenix LiveView and HTML, reducing latency and aligning UI patterns for more consistent and responsive interactions.

May 1, 2026

In May 2026, focused on improving copy token UX in OpenFn/lightning with a client-side, reliable tooltip solution, reducing latency and visual glitches, and aligning with existing UX patterns. Key work included a robust tooltip feedback loop for copy tokens, UI fixes for clipping and flicker, removal of an unnecessary server round-trip, and changelog documentation for #2463. This delivered tangible business value by reducing user confusion, speeding copy actions, and improving consistency across the app.

Summary for 2026-03: Implemented GeoJSON AOI Parser Integration for hotosm/drone-tm, enabling robust AOI handling by accepting all GeoJSON formats and merging multi-feature inputs into a single polygon. Introduced geojson-aoi-parser and normalize_aoi dependencies and migrated AOI normalisation to PostGIS-based operations (ST_UnaryUnion, ST_Difference), replacing shapely merges. Added regression tests for multi-feature FeatureCollection handling and updated TaskSplitter/preview_split_by_square flows. This work reduces AOI parsing errors, improves reliability of AOI-based tasks, and enhances downstream processing performance. Also included pre-commit fixes and dependency lock updates to improve CI reproducibility. Coherence with commit 70c83fe555dab8a549bfb163d5c19e6ece940f89 (fix(#735)) and related changes.
