Jeyoon contributed to the Techeer-Hogwarts/nest repository by building and enhancing backend features focused on API reliability, security, and scalability. Over two months, Jeyoon implemented access control for Swagger documentation, stabilized TypeScript tooling, and improved build and deployment workflows using Docker and DevOps practices. They strengthened user profile management by standardizing API responses, refining input validation, and updating the Prisma schema for better data integrity. Jeyoon also integrated AWS S3 for media uploads and introduced Redis-backed caching to support scalable study announcements. Their work demonstrated depth in TypeScript, NestJS, and cloud storage integration, resulting in robust, maintainable backend infrastructure.
