WPS Online Editor
A web-based rich text editor for users to create beautiful and rich content directly from a browser and share it with the social network. The major highlight of this project is that it is completely compatible with Microsoft Word document format, which allows users to import their word documents directly into the editor while preserving the original format and layout. I was the architectural designer and main front-end developer of this project.
