September 2025 — Konkuk-KUIT/KUIT6_WEB-Frontend: Key user-facing feature delivery, accessibility, and repo hygiene improvements. Delivered a mobile-like User Profile & Introduction experience (personal introduction page and 'My Carrot' profile with payments, transactions, and neighborhood activities).
