October 2025: Strengthened data quality and project hygiene for arvindkrishna87/STAT390_LegalAid_Fall2025. Delivered an end-to-end data cleaning and preparation pipeline in R, standardizing column names, enforcing correct data types, and imputing missing values with domain-aware defaults. Implemented session-context and timestamp-based logic to infer ep_name and flow_name, preserving data integrity for downstream analytics. This reduced preprocessing time and improved consistency across datasets used in legal aid research. In parallel, completed repository maintenance to ensure documentation is current and the repo is clean: updated PDF documentation, added a PowerPoint presentation, and performed metadata cleanup (e.g., .DS_Store updates). These efforts enhance reproducibility, onboarding, and governance while delivering tangible business value through more reliable analyses and streamlined collaboration.
