Created tax region seed data (e.g., State-level, Country-level, International regions) with attributes like code, description, and applicable jurisdictions.

Developed tax rule seeders defining tax rates, conditions, and applicable regions to automate tax calculations in the system.

Ensured relational mapping between tax regions ↔ tax rules to maintain accuracy and consistency in seeded datasets.

Automated the data loading process to populate these values during database initialization or migrations.

Verified that seeded tax data was visible and functioning correctly in the application’s grid and business logic modules.
