$30/hr Starting at $250

I am a WebMaster with over 3 years of professional experience specializing in React.js development, building scalable and modern web applications. My expertise includes Redux for state management, Umi framework, server-side rendering, GraphQL/Apollo, and REST API integration. I have worked with both CRA projects such as Divi Project and Stanza, as well as Gatsby for highly optimized static sites like MakerDAO. With a strong background in frontend architecture and performance optimization, I deliver clean, maintainable, and user-friendly interfaces while collaborating effectively with cross-functional teams.
