Feb 1, 2026February 2026: liia-tools-pipeline focused on data quality and stability. No new features delivered this month; a critical bug fix standardizes missing-value handling in time series by converting blanks to pandas NaT (pd.NaT) to avoid empty strings downstream. This reduces downstream errors and improves reliability for analytics and reporting. Technologies demonstrated include Python, pandas, and Git-based workflow; strong emphasis on data-quality engineering and reproducibility.
