Worked on the OneKeyHQ/app-monorepo, focusing on enhancing onboarding, UI clarity, and navigation consistency across web and Perps contexts. Delivered three features that streamlined wallet connection by introducing a context-aware connect button, refined device management with a more intuitive plus icon for adding devices, and improved header navigation through localized buttons and toolbar unification. Leveraged React for front end development, utilizing both JavaScript and TypeScript to implement localization-ready patterns and centralized UI behaviors. These changes reduced onboarding friction, improved discoverability, and enabled faster iteration cycles, resulting in a more coherent and maintainable user experience across multiple platforms within the monorepo.
