I'm Matheus Barcelos, a front-end and full-stack developer with experience across streaming, e-commerce, banking, Web3, and AI. I’ve led front-end architecture, integrated complex platforms (including Disney Movies Anywhere), and contributed to migrations between Angular, React, and Next.js. I have built multi-tenant systems and real-time AI experiences with streaming responses, delivering scalable, high-quality products. I focus on clean architecture, maintainability, and delivering robust user experiences. I’ve migrated projects from Angular to React/Next.js and integrated Gatsby, Contentful, and Amplify into banking-app websites, improving user experience and performance monitoring. As a full-stack developer, I work across front-end and back-end, including security enhancements, migrations, and modern UI interfaces, and I’m actively contributing to Web3 platforms with React and Node.js.…I'm Matheus Barcelos, a front-end and full-stack developer with experience across streaming, e-commerce, banking, Web3, and AI.
