Session Goal

The session aimed to develop and refine an ETL pipeline for financial data processing, including data extraction from Google Sheets, transformation, and CSV report generation.

Key Activities

  • Analyzed the AF447 disaster for critical decision points and human factors.
  • Reviewed MH370 search developments and aviation theories.
  • Compared flight simulation platforms for realism and crash simulation.
  • Developed a recipe for Argentine-style salsa criolla.
  • Created a systematic approach for coin classification and cleaning.

  • Documented ETL flow for financial reporting.
  • Created data flow diagrams and Mermaid diagrams for documentation.
  • Outlined a one-click ETL and analysis regeneration system.
  • Implemented Python scripts for ETL pipeline, focusing on data processing from Google Sheets.
  • Addressed issues with PeriodIndex to Datetime conversion and column selection in ETL scripts.
  • Resolved ValueError in CSV export and adjusted time period indexing in financial pivot generation.

Achievements

  • Successfully developed a comprehensive ETL pipeline script (run_etl_pipeline.py) for financial data processing, including time series data generation and CSV export.
