Experience

Now

• 1^st January 2020 – present

  Full Stack Developer at Ricker Lyman Robotic

  • build, test, and deploy an application written with React + Apollo Client → Node.js + Express + Postgraphile + PostgreSQL
    (the project is alive, hence backend packages are not listed)

    @apollo/client @auth0/auth0-spa-js @fortawesome/react-fontawesome @material-ui/core @material-ui/lab @optimizely/react-sdk @umijs/hooks classnames date-fns file-saver formik graphql history lodash mapbox-gl material-ui-popup-state notistack react react-copy-to-clipboard react-dom react-map-gl react-papaparse react-refresh react-router-dom react-scripts react-window react-window-infinite-loader subscriptions-transport-ws yup
  • keep dependencies up-to-date, code clean, linted, and prettified (also solid, dried, and kissed)
    eslint-plugin-import eslint-plugin-prettier eslint-plugin-simple-import-sort husky lint-staged prettier source-map-explorer
  • make the app beautiful, themable (using Material UI and Font Awesome), and reactive (using Websockets API)
  • integrate with third parties (e.g. Auth0 for authentication, Optimizely Rollouts for feature flags, etc.)
  • keep code coverage threshold for unit tests at a reasonable minimum (it's 0% so far)
  • optimize the code for performance and efficiency (use Service Workers API, Web Workers API, and techniques like memoization, throttle and debounce to solve caching, overfetching/underfetching, exceeding rate limits, unnecessary rerendering, and browser freezing issues, etc.)
  • keep backend robust and steady (using axios-retry to retry calls, winston for logging, and lightship to report readiness and liveness, etc.)
  • wrap those into Docker containers and deploy to Kubernetes as part of the microservice-based architecture, check CI/CD pipelines for speed, reliability, and consistency
  • communicate with other microservices using Kafka or REST APIs
  • try and maintain a proper attitude, being soft yet reasonable and persuasive, set realistic deadlines and goals and help the team to meet those, lead by example
