June 1, 2025 A containerized full-stack application for computing Pakistani income tax based on multiple parameters. The Node.js/Express backend implements the business logic for tax calculation rules and persists tax data in PostgreSQL. The React frontend provides the user-facing interface. Both services are orchestrated with Docker Compose for streamlined local development.
Key design decisions: modular architecture with clear separation between calculation logic and data access, PostgreSQL schema designed around tax brackets and user inputs, and Docker Compose for reproducible environment setup.
