🕒 20:20–21:55
🏷️ Labels: ETL, Accounting, Data Platform, Automation, Python
📂 Project: Accounting

Session Goal: The session aimed to develop and integrate a defensive wrapper script for materializing accounting artifacts, review existing accounting scripts, and design a comprehensive ETL pipeline and accounting data platform.

Key Activities:

• Created a defensive wrapper script scripts/materialize.py for materializing accounting artifacts and integrated it into a Makefile.
• Reviewed accounting scripts and system components, focusing on function implementations and CLI entrypoints for ETL processes.
• Outlined a structured plan for assembling ETL modules, identifying existing components and gaps, and providing actionable code snippets.
• Designed a practical accounting data platform, detailing responsibilities, scheduling runs, and ensuring outputs are correct and auditable.
• Developed an operational design for weekly and monthly accounting runs, including artifact contracts, cadence design, and validation checks.
• Compiled a compact playbook for the accounting data platform, emphasizing a single source of truth and governance through manifests and validation checks.
• Outlined a workflow for transforming raw ledger data into a canonical format, including validation checks and edge-case considerations.

Achievements:

• Successfully created and integrated a defensive wrapper script for accounting artifact materialization.
• Established a detailed plan for ETL pipeline assembly and accounting data platform design.
• Developed operational designs and playbooks to ensure auditability and governance.

Pending Tasks:

• Implement the full ETL pipeline based on the outlined plan.
• Finalize the integration of all components into the accounting data platform.
• Conduct thorough testing and validation of the entire system to ensure accuracy and reliability.
