During June 2025, contributed to the seolhee-choi/B2B-Demo repository by establishing a robust project foundation with a Spring Boot backend and Vue frontend. Developed a secure, end-to-end authentication flow featuring email-based login, persistent sessions, secure cookies, and logout, all with explicit cross-origin support. Implemented client-side state persistence using Pinia PersistedState and standardized application behavior through shared utility and validation modules. Enhanced repository hygiene and introduced initial query logging to support maintainability and observability. Leveraged Java, JavaScript, and SQL to deliver a scalable, security-focused architecture that improves onboarding, user experience, and sets the groundwork for rapid future feature development.
June 2025 – seolhee-choi/B2B-Demo: Established a solid project foundation and security-ready authentication flow, setting the stage for rapid feature delivery. Key features delivered: a clean backend/frontend skeleton (Spring Boot + Vue) with repository hygiene and initial observability (query logging). Implemented end-to-end user authentication (email login, persistent session, secure cookies, withCredentials) with logout and cross-origin support. Enabled client-side state persistence via Pinia PersistedState and introduced shared utilities and validation utilities to standardize behavior. Strengthened infra for security and UX with explicit CORS configuration and early caching of user info in localStorage. Impact: improved onboarding, more secure and stable UX, and a scalable base for future features. Technologies demonstrated: Spring Boot, Vue, Pinia PersistedState, CORS, withCredentials, localStorage, and modular utility design.
