Experience
- Crypto Dashboard
This crypto dashboard is a React and Redux SPA application that queries data from various cryptocurrency APIs and displays that data in an easy-to-read and search format. This was a personal front-end-only project that I did in order to gain more experience using Redux Toolkit to manage data gathered from API fetches.
- Club Website
This is a React, Node.js, and Express full-stack application for team management and event scheduling. As a full-stack developer, I implemented various back-end APIs and data management features, including socket connections for a group chat using SocketCluster API. I also developed front-end features in React, including chat windows, data report pages, and individual voting pages.
- Portfolio Website
This is a static webpage with a React front end and Google Firebase back end. This webpage displayed key information about my website development experience and projects. As the sole developer, I designed, developed, and continually maintained the web page.
