About

I’m a Frontend Developer with 5+ years of experience building scalable, high-performance web and mobile applications. I specialize in React, Next.js, Astro, React Native, and TypeScript, helping businesses create fast, responsive, and conversion-focused e-commerce experiences. I also leverage AI-assisted development tools with a Spec-Driven Development approach to boost productivity and code quality.

Currently, I contribute to multiple large-scale digital platforms, where I develop new features, optimize performance, and build landing pages designed to increase user engagement and sales. I have strong experience with state management (Context API, Redux-Saga, Zustand), testing (Jest), and modern styling solutions (Tailwind CSS, Styled Components). I hold an Associate Degree in Systems Analysis and Development from Cruzeiro do Sul (2021–2022).
