During February 2025, work focused on delivering two core API features for the Techeer-Hogwarts/nest repository. The developer implemented a Retrieve Blog Post by ID API and a Technology Stack Creation API, both designed with a layered architecture using NestJS and Prisma. Each endpoint included comprehensive validation, persistence logic, and unit tests to ensure reliability and maintainability. End-to-end tests were added to further guarantee robust functionality. By emphasizing RESTful design principles and test-driven development in TypeScript and SQL, these features improved content retrieval user experience and streamlined onboarding for new technology stacks, while enhancing data integrity across the backend system.
