Full Stack Open 2021

A submission repository for the University of Helsinki's Full Stack Open 2021 course, which teaches React, Redux, Node.js, MongoDB, GraphQL and TypeScript. This course introduces modern JavaScript-based web development. The main focus is on building single page applications with ReactJS that use REST APIs built with Node.js

Over Winter 2021, I completed 8 ETCS credits, whereby I used 171 hours! It was truly an enriching experience where I could polish and refine my web development skills, and at the same time learn best practices and new technologies.
