TodoMall (투두몰, meaning "challenge mall") is the product I built at MyPlanIt as co-founder and CTO. The tagline: "세상의 모든 도전이 쉬워지도록" (making every challenge in the world easier).
The thesis: long video lectures are expensive to produce and painful to skim. Experts should be able to author curricula as a sequence of short text + image lessons, and learners should be able to work through them as a to-do list — checking off each step as they go.
Built with Next.js + TypeScript. Emotion for styling, React Query for server state, Redux Toolkit for client state, Storybook for the design system (auto-deployed via GitHub Actions so design could review UI without a local setup). Kakao Login for quick onboarding. SSG on the product detail pages so commerce loads fast even on cold visits.
