Kelvin Maués is a Senior Software Engineer based in São Paulo with a decade of experience building and scaling web and mobile applications using JavaScript and TypeScript, particularly React, Next.js, React Native, GraphQL, and Node.js. He has driven product-level engineering at companies like iFood, leading architecture, backlog planning, and cross-team delivery while mentoring juniors and running code reviews. Kelvin blends front-end craftsmanship (Storybook, design systems, Chakra/Material UI) with back-end integrations (REST, GraphQL, WebSockets) and pragmatic testing practices (Jest, Testing Library). He has hands-on experience implementing micro front-ends, A/B testing for UX optimization, and building shared UI libraries—skills that reflect a product-minded engineer who balances developer experience with measurable user outcomes. Notably, he has practical startup and community roots—from organizing local dev conferences to shipping production mobile apps using Firebase and single-spa—bringing both leadership and scrappy execution to teams.
