Created and maintained a private GitHub repository for the interns, added new features and improved existing features of a campaign-funding data visualization tool, made QoL changes, created a WordPress site that would serve as an entry point to the tool, suggested further improvement paths. The application was mostly built using JavaScript and React.js, which were new to me. The website and the engine are still under development.
