  • Bubbles

    A TypeScript-based app that uses user-input sources to generate enriched content for asynchronous communication. It uses conflict-free replicated data type (CRDT) with a Redux (server and client) architecture.

    I worked on the transcripts feature and improved the UI, layout, and components for a "bubble."

    A React-based app for time and calendar blocking and productivity-boosting.
    I worked on the back end, and front end, but I spent most of the time maintaining and adding React components and the Chrome extension features.

  • Knowbly

    A web application built mainly with Vue.js and Loopback.js for next-generation interactive content authoring and e-learning widgets creation platforms.
