During March 2025, David stabilized the core analytics pipeline in the radiocosmology/draco repository by addressing a crash in the Null Delay Filter, replacing the deprecated NumPy freq.ptp() with np.ptp(freq) to ensure compatibility and reliability. He also improved repository hygiene by updating the .gitignore to exclude editor backup files. To streamline onboarding and maintenance, David revised the installation documentation, directing users to install via pip and removing outdated setup.py references. His work demonstrated proficiency in Python and NumPy, with a focus on bug fixing, documentation, and clear technical communication, contributing to more robust deployment and downstream data processing.
