Worked with a team of students to develop a full-stack scheduling platform to help with donation pickups and drop-offs for the nonprofit Habitat for Humanity, San Luis Obispo County. We used the MERN Tech Stack with our front-end primarily built with React.js and our back-end with Mongoose and Express using RESTful API practices. This project furthered my experience coding in javascript, typescript, HTML5, & CSS and using the Node Packet Manager (NPM).
