Worked on the gridstatus/gridstatus repository to expand NYISO data coverage through 2024 and 2025, focusing on enhancing data completeness and reliability for business analytics. Updated capacity data URLs and adapted data processing logic to accommodate new data schemas, ensuring year-over-year comparability of NYISO metrics. Leveraged Python and SQL to build and adjust data ingestion pipelines, while integrating robust API connections and automating tests to cover the expanded datasets. Emphasized data engineering best practices and continuous integration, with all changes passing CI tests. The work prioritized data-source expansion and test coverage, with no major bugs reported during the development period.
