Music Repository

Designed the system architecture for an academic repository, enabling the systematic preservation and cataloging of large-scale musical assets.

Designed and developed a production-ready, secure RESTful API backend for a higher education institution to manage, filter, and distribute digital music education assets. Built with Node.js and Express, the platform handles automated pagination, relational data synchronization, and multi-file attachment payloads over a secure server infrastructure.

Managing multi-table relational dependencies (such as linking courses, user roles, metadata tags, and multiple documents) without causing memory leaks or slow database query responses. The system required an enterprise-grade connection configuration capable of handling concurrent requests to a PostgreSQL database, secure environment variable routing (.env), and a clean, structured JSON API payload formatting for smooth frontend consumption.

Engineered a scalable MVC backend architecture utilizing a multi-client connection pool (pg.Pool) to handle high-performance database transactions efficiently. I implemented modular Express routing to segment business logic and developed complex relational queries with optimized joins to fetch, format, and paginate structured academic data. All infrastructure secrets and keys are isolated using strict environment configuration standards to ensure deployment safety.
