Simplifying Loyalty and Rewards Management in Retail Health
#MERN, #customsoftware, #gamechanger
The client needed a robust, easy-to-use web application for their loyalty and rewards program that would help towards increased adoption. The application would have to ensure secure transactions and integrate seamlessly with third-party systems.
Solution
We developed a scalable web application for the client using NodeJS, Express, NestJS, NextJS, PostgreSQL, typeORM, and TypeScript. Our solution adhered to clean architecture principles and employed the CQRS design pattern. We used OpenAPI for seamless integration of our application with healthcare systems, vendors, and third-party services. We used OpenID to handle authentication, and OAuth with custom roles and permissions for authorisation. The application was hosted on AWS, following the OWASP Application Security Verification Standard to secure sensitive data. Our solution has led to widespread adoption and customer engagement. Millions of reward points have been issued and redeemed since 2019 when Pooja Points launched our application.
