E-learning App Web App - Responsive and SEO

I need an experienced UI UX designer to help build an e-learning app targeting students. The emphasis should be on creating engaging and intuitive designs promoting interactive learning modes of Quizzes & Assessments, Interactive Lectures and Collaborative Learning Tools. The color scheme should veer towards a minimal and clean style. Strong knowledge of current UX design principles is crucial, as well as experience in designing educational or e-learning platforms.
