We're developing a digital invitation product that enables customers to effortlessly create personalized invitations. We're using NextJS for the frontend, known for its performance and interactive user interface. For the backend, we've chosen NestJS, which offers scalability and clean architecture for efficient development. In addition, our platform integrates a secure payment gateway, allowing customers to conveniently make payments for their customized invitations. This ensures a seamless user experience while maintaining code quality.
