Developed a Product Catalog API for the elascano/ESPE2410-AWDSW2296 repository, focusing on centralizing product data for consistent access across services. The solution was built using Express.js and Node.js for the backend framework, with MongoDB providing persistent storage. A dedicated products schema was implemented to structure catalog data, and a GET endpoint was created to retrieve all products efficiently. This work established a scalable backend foundation, supporting future enhancements such as search and filtering. The integration of MongoDB connectivity and data modeling addressed the need for reliable catalog listings, with all changes tracked and documented through a single, traceable commit.
