In January 2025, Bhattacharya contributed to the masa-umich/Rocket-Avionics repository by developing a height data demonstration file to support more reliable and repeatable testing workflows. Using Python and Git, Bhattacharya implemented an example height data file and addressed a data ingestion issue by aligning input filenames with program expectations, which improved the consistency of data discovery during automated tests. The work focused on enhancing the reproducibility of height data processing, enabling faster quality assurance cycles and clearer demonstrations. Bhattacharya maintained concise, focused commits throughout, reflecting a methodical approach to risk management and code review in a short project timeframe.
