I will teach you how to design and develop great user experiences (UX) for your website or applications (web and mobile). My teaching is very flexible. But it make sense to start with key elements of a great UX, learn about HTML, CSS (TailwindCSS, SCSS, SASS), Javascript (Angular, React, NextJS). There is no fixed plan, because technology differs from project to project. A web application can be statically generated (SSG) or full-stack (frontend and backend). I have experience building both. My aim is to teach the topics which are the most beneficial for the student. Looking forward!
