Development of modern, accessible, and scalable web interfaces that add value to digital products.
Looking for a frontend developer who combines clean code with a polished user experience? I transform designs into robust applications with React and TypeScript, built to last and evolve with your project.
Beyond development, I contribute to making projects work better:
- Improvement of frontend processes through reusable components and more consistent systems, facilitating product evolution.
- Technical organization in complex projects, bringing clarity and alignment between design, business, and development.
- Detection and resolution of performance, accessibility, and maintenance issues before they escalate.
- Optimization of user experience, identifying friction points and proposing clearer and more accessible interfaces.
- Application of good SEO and performance practices in projects with business impact.
- Rapid adaptation to new environments, tools, and project needs.
- How can I help you
- Development of SPA and SSR applications from scratch
- Creation of design systems and component libraries (Storybook)
- Migration and modernization of legacy code
- Integration with REST APIs and performance optimization
- Accessibility audits (WCAG AA)
I work in Agile environments, with clear communication and iterative deliveries. My background in communication and marketing allows me to document technical solutions in a way that is understandable to multidisciplinary teams.
