Stephen held a career in entertainment management for over a decade. In 2018, it became clear that tech and entertainment were colliding, so he decided to learn how to code. After finishing a one-year immersive full-stack bootcamp, he immediately landed an engineering role in public transportation, working with everything, from physical hardware to detailed CSS. Stephen has developed a passion for JavaScript and is eager for the next adventure.

  • Screens

    A fully responsive React SPA that displays arrival times and info at bus terminals. The primary challenge was that we could not control the quality or aspect ratio of the screen we were to display it on. We were forced to assume an unknown aspect ratio with screen sizes between 1/4 of 240p and 4K resolution. Our solution was a completely scalable, aspect ratio-dependent, responsive page far outside the range of standard screen resolutions. Our app scaled from 40 to 4,000 pixels in width. It also scaled the displayed information according to the aspect ratio and the number of pixels it could work with, from one arrival time or bus bay of two to six characters to dozens of bays, buses, and times, with information about the next arrival and destination. To meet one of the more in-depth requirements, I authored a library to scale, wrap, and fit text inside a container to display the text at its maximum font size without overflow, given any particular font.

  • React Moderization

    I refactored and updated the GMV's flagship, a 150+ component React app from Node.js 6 on Alpine to Node.js 14 on Alpine. It allowed updating 50+ appropriate npm packages, removing unneeded packages, and auditing the rest, taking security issues from 1,000+ to 0. Additionally, I took all React components from class components to Hooks and added and modernized ESLint and Stylelint. I also integrated development, build, and publishing pipelines in webpack to help future-proof the project from developer drift while maintaining a functional product under very active development. As a result, 80% of the project received massive overhauling.
