Jun 1, 2025June 2025 monthly performance summary for SocialFinanceDigitalLabs/liia-tools-pipeline. Key features delivered and stability improvements were achieved through cross-platform packaging enhancements and platform-aware dependency management, complemented by a robust fix to UTF-8 BOM handling. Specifically, we updated poetry.lock for liia-tools-pipeline-config and added a Windows AMD64 wheel for psycopg2-binary to improve deployment reliability and cross-platform support. Major bugs fixed included a BOM-aware UTF-8 decoding fix to prevent parsing errors and data corruption, using utf-8-sig. These changes contributed to more reliable builds and smoother CI/CD across environments. Skills demonstrated include Python packaging (Poetry), cross-platform wheel distribution, dependency management, and encoding robustness, all translating into tangible reductions in deployment friction and data integrity issues. Business value: faster, more reliable deployments; improved data integrity; and a stronger foundation for scaling pipelines.

Jan 1, 2025January 2025 focused on strengthening Annex A handling in the liia-tools-pipeline. Delivered robust schema and header processing by migrating YAML parsing to ruamel.yaml, normalizing schema entries, and implementing case-insensitive, whitespace-stripped header comparisons with a robust regex for child ID headers. Added comprehensive tests and enhanced logging to improve traceability of data flows. Implemented safeguards to prevent Annex A datasets from flowing into final outputs by excluding them from move_current_org and move_concat. Removed deprecated school census processing code to reduce maintenance burden and potential confusion. These changes improve data quality, pipeline reliability, and maintainability, enabling safer, faster onboarding of schema improvements and future enhancements.
