Portfolio

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."

KosmoTime

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.The biggest one I worked on is the calendar, where we can block tasks, sync Google calendar events, drag in and out custom components of the app, etc.

Knowbly

A web application built mainly with Vue.js and Loopback.js for next-generation interactive content authoring and e-learning widgets creation platforms.I was a JavaScript engineer in charge of building and maintaining core features of the app, including the attachment block on course creator, the notifications service, the layers editor, the global files upload modal, and all of the components of the course creator, a key feature of the app.
