Over a two-month period, contributed to the data-hydenv/data repository by developing and expanding environmental data ingestion features focused on time-series temperature monitoring. Built a standardized 10-minute interval CSV data feed with normalized timestamps, improving analytics reliability and simplifying downstream ETL processes. Extended the dataset with an hourly temperature CSV that included timestamps, temperature readings, and an origin indicator to enhance data completeness and provenance. Employed skills in data engineering, data cleaning, and data formatting, working primarily with CSV files. The work emphasized schema consistency, reproducibility, and compatibility with analytics pipelines, addressing data quality and ingestion challenges without introducing bug fixes.
