Your stack (Next.js, Express.js, and PostgreSQL) is solid, but NestJS might be a better choice than Express.js.

NestJS provides better structure, scalability, and built-in features like authentication and dependency injection. Plus, since it uses TypeScript, your frontend and backend can share the same language, making development smoother.

If you want a more maintainable backend, NestJS is highly recommended.
