As a full-stack engineer, I led the development of Eclatly - Kids Learn French, a custom SaaS application designed to provide children with an engaging platform for learning the French language. Collaborating closely with design and product teams, I conceptualized and implemented a comprehensive solution that includes interactive lessons, games, and activities tailored to young learners. Leveraging modern technologies and best practices, I developed intuitive user interfaces, integrated third-party APIs for enhanced content, and ensured seamless functionality across the frontend and backend. Through thorough testing and ongoing support, I delivered a dynamic learning experience that fosters engagement and retention among children, receiving positive feedback for the platform's innovative features and user-friendly design.
