Experience
Punching Pixels
https://punchingpixels.us/Diderot
https://www.diderot.one/Social Coach
I designed CSS templates for use on all pages of the website. This functioned with the CSS background, positioning, text, border, margin, padding, and table. I used React-Router to turn the application into a single-page application and React JavaScript components, forms, events, keys, router, and animations. I transmitted large blocks of JSON with RESTful web services, created a responsive design, and developed a single isomorphic responsive website that worked on desktop, tablets, and mobile using React. Maintained states in the stores and dispatched the actions using Redux. Created and used reducers that received said actions to modify the store state tree—collaborated with back-end engineers to optimize existing API calls to create efficiencies by deprecating unneeded API calls. Used object-oriented programming concepts to develop UI components that could be reused across the web application. Extensively used Git for version control and regularly pushed the code to GitHub.
