Jinyeong Seol

Worked on the toss/frontend-fundamentals and spring-projects/spring-security repositories, delivering features and fixes that improved UI theming, localization, and authentication reliability. Enhanced the frontend by implementing theme-aware UI updates, dark mode support, and standardized policy terminology, using technologies such as TypeScript, Vue.js, and CSS. Improved documentation clarity and localization quality in both Japanese and English. Addressed frontend bugs by refining import syntax, error messaging, and authentication header consistency. On the backend, strengthened the JdbcOneTimeTokenService in Spring Security with reliable token deletion feedback and concurrency-aware tests, leveraging Java and the Spring Framework to improve multi-threaded robustness and authentication predictability.
