• Advanced Validation: Schema-based input validation using zod.
• Database Seeding: A script to automatically create an admin user.
• Centralized Error Handling: A single middleware to handle all application errors gracefully.
• Pagination: Scalable endpoints for fetching lists of data.

• Backend: Node.js, Express.js
• Language: TypeScript
• Database: PostgreSQL
