Chang Yong Mun | Portfolio

Name: Chang Yong MUn

I have a solid understanding of TypeScript’s type system, including generics and type inference. By leveraging these features, I have improved type safety and achieved better code readability and maintainability.
I have a strong understanding of how Vue, Nuxt, React, and Next work, particularly in terms of data binding, state management, and component lifecycles. I have experience applying SSR and CSR appropriately based on context, and have successfully debugged and resolved issues that occurred in real-world services.
Designed reusable components to minimize code duplication and enhance development efficiency in collaborative projects.
Improved First Contentful Paint (FCP) by 23.8% in the Cupicks project by optimizing performance based on a deep understanding of the rendering process, Lighthouse metrics, and customer feedback.
Automated repetitive deployment tasks and implemented a CI/CD pipeline using Bitbucket, Jenkins, and GitHub Actions, resulting in reduced deployment time and significantly improved team development efficiency.
