Hello! I'm Mariana Silva Senio, a Senior Frontend Developer specialized in React and Next.js, with over 4 years of experience delivering high-performance web applications from concept to production. I have advanced knowledge of React hooks, Context API for global state management, TypeScript, and building reusable components from scratch. I routinely integrate REST APIs with Axios, tailor user interfaces with Bootstrap and Tailwind CSS, and I deeply value CSS craftsmanship, Git version control, and Agile methodologies such as Scrum and Kanban. I also have solid experience with automated testing using Jest and React Testing Library to ensure reliable, maintainable, and well-tested code. I'm known for managing priorities under tight deadlines and delivering solutions focused on performance and excellent user experience. I’m passionate about mentoring junior developers and promoting collaboration, knowledge sharing, and code quality. I've contributed to AI integration and Google Cloud authentication on strategic projects, and I enjoy shaping robust frontend architectures and scalable component libraries. I'm comfortable working across design, backend, and cross-functional teams to deliver polished, user-centered software.…Hello!
