During January 2025, No An developed foundational data ingestion workflows for the data-hydenv/data repository, focusing on temperature time-series datasets. They designed and delivered two structured CSV files—one capturing 10-minute intervals and another with hourly readings—each including columns for id, timestamp, temperature, and an origin indicator to support historical logging and analytics. Leveraging data engineering and data logging skills, No An established clear dataset schemas and directory structures to enable repeatable analytics pipelines. Although the work spanned a single feature with no reported bugs, it laid essential groundwork for future time-series analytics and robust data ingestion processes within the repository.
