Strong React and modern frontend experience (Redux Toolkit, Material-UI, hooks, component composition, JavaScript/TypeScript). Experience working with LLMs and AI-driven UIs (streaming responses, loading states, chat interfaces). Strong product mindset, thinking about user flows and feature integration. Deep care for UI/UX details, building smooth and intuitive interfaces. Some backend experience (working with REST APIs, understanding data models). Comfortable working in an early-stage, ambiguous, and fast-paced startup environment.
