Projects

• Got 'Emabout.gotem.live
  • Mobile Web
  • React
  • NodeJS
  • Express
  • GraphQL
  • PostgreSQL
  • Websockets

  A social game for people to gather around the TV and play with their friends. Built with a React frontend, Express backend, GraphQL and Pusher-powered websockets. Deployed with Netlify and Fly.io.

  A collaboration with my friend who built the Apple TV app using the same web backend.

• 🏺Amphora View Project
  • React
  • NodeJS
  • Express
  • GraphQL

  A work hackathon project, Amphora was an internal deployment platform. It automatically deployed a full replica of a three-repo stack, including an isolated database, with fully customizable branches for code and Kubernetes infrastructure.

• 🎛️Playbook / Reach OutsView Project
  • Contentful App
  • GraphQL Introspection
  • Custom Templating Engine
  • Rules Engine

  The Playbook and Reach Outs tools were offered to a wine selling community. I built a sophisticated backend and rich administration interface for the home office team to easily customize behaviors. For example, a "Playbook Card" could be configured to publish to any seller who enters a given Segment audience, then archive itself and give the seller reward points when they interact with it on the website.

• 🥞Custom Job QueueView Project
  • PostgreSQL
  • Horizontal Pod Autoscaling
  • Code Generation

  After not finding a developer-friendly NodeJS job queue that fit my team's needs, I developed a custom one — simple at first, but now processes ~200,000 jobs per day with multiple queues, automatic retries, and demand-based worker autoscaling.

• Clusterverseclusterverse.app
  • macOS
  • Swift
  • DigitalOcean REST API

  My foray into macOS development, Clusterverse makes it easy to manage your Kubernetes context from the Mac menu bar. Integrates with the DigitalOcean API for one-click auth into DOKS clusters.

• 🚦Throttled Fetch ServiceView Project
  • NodeJS
  • Redis
  • lodash

  To solve the problem of many distributed app instances requesting data simultaneously, I created a service that is essentially a wrapper around lodash.throttle along with library code to make it trivial to use in any NodeJS app. This cut down around 90% of redundant requests in a few of the hottest endpoints while still keep data fresh.
