Jungcome Lee contributed to the chainapsis/keplr-wallet and keplr-chain-registry repositories, focusing on front-end architecture, blockchain integrations, and design system foundations. Over five months, Jungcome delivered features such as governance data querying, USDC support on StarkNet, and CoinGecko API integration for market data. He established a scalable design system using React, TypeScript, and Storybook, automating Figma token extraction and enabling centralized theming. His work improved UI consistency, onboarding flows, and localization, while also enhancing CI/CD reliability and documentation. The engineering approach emphasized modularity, maintainability, and robust state management, resulting in a more stable and extensible wallet platform.
March 2026 — Chainapsis/Keplr Wallet: Established a scalable design-system foundation, automated UI previews, and enhanced theming, delivering concrete business value through UI consistency and faster feature delivery. Implemented core DS scaffolding and workspace initialization, upgraded Storybook to support previews/docs, and enabled automatic GitHub Pages deployment for design-system assets. Built a comprehensive Figma-to-token pipeline (figma-extract-vars.mjs) with token and primitives syncing, generating DSColor tokens, DSTypography tokens, 96 icon components, and typography tokens. Integrated DSThemeProvider into AppThemeProvider to enable centralized theming and external theme support. Performed targeted UI polish including adding a Setting icon to the account switch modal and aligning icons with new design guidelines.
