My Journey & Experience
Complementing my Node.js adoption, I began working with Express.js in 2022 to build lightweight RESTful services and prototype APIs for full-stack apps. While my early projects involved basic routing and demo services, my mastery deepened significantly in 2025 during the Web Programming course at Sejong University. There, I architected comprehensive Express applications with production-grade middleware pipelines, robust authentication flows, rate limiting, error handling, and structured database integrations.
