    I develop and enhance enterprise frontend applications using React and TypeScript, implementing new features and optimizing the user interface. I integrate REST and GraphQL APIs for data management, workflows, and business operations in complex applications. I optimize performance by reducing load times by 40% through lazy loading, code splitting, and dependency reorganization. I lead the migration of legacy JavaScript applications to TypeScript, setting the standard for new developments. I maintain applications both evolutively and correctively, ensuring performance and scalability, including issue resolution and refactoring. I coordinate projects and mentor junior developers and interns in multidisciplinary teams under Agile methodologies.
