UvA Collaboration Tool

Project Overview

The UvA Collaboration Tool is a Vue.js-based application I developed between 2017-2018 for content managers at the University of Amsterdam. It enables users to exchange information about individual pages across their websites. The project focuses on high performance to handle tens of thousands of pages and hundreds of interactions per page.
