The Project

In Romania, we are developing applications related to calendaring (where we integrate Cosmo, a CalDAV server implementation which we made open-source), document editing (where we integrate Libre Office Online, an open-source project to which we contribute), messaging and web hosting.

Office Online is a productivity application, MS Word, MS Excel, MS PowerPoint compatible web application hosted on the webde and gmx portals. Its target audience is each of the 39 million customers who use our portals monthly. It is offered as a free service to edit Office documents stored on customer’s cloud drive as well as email. The use cases are very similar to Google Docs/Sheets/Slides.

The application is based on Libre Office Online, an existing open source office solution currently under heavy development. The project consists of integrating and customizing the application within our portal and our brands, as well as contributing to the open source code base and following up with the Open Source community.

Office Online is a two parts project: the frontend is written in JavaScript while the backend, supported by a custom made web socket server, is entirely written in C++. The product is deployed on a Docker / Kubernetes infrastructure with integrations done in Java.
