Development of a Trade Convention App

Using React and Node.js, we created a web application to accompany product sampling at trade conventions for a large engineering company.

Visitors were able to use the application on tablets or mobile devices. The display was optimized for various screen sizes using responsive design. Users rated various product qualities, while the currently selected rating was attractively visualized. Afterwards the application processed and analysed the answers, presenting users with a comparison of their rating with the average of all previous ratings.

Elastic Stack Upgrade

TNG performed an upgrade of the central Elastic Stack for company-wide logging at a large insurance company. This was a two-stage process, using an intermediate version to reach the latest version. It was the first upgrade of this system altogether and had to be executed manually, without central server management, on each server. At the same time, 6TB of production data in the stack was moved to new hardware. Despite these large scale changes, the effects on users were very small.

LEGO Millenium Falcon World Record

Inspired by the Heise Livestream, a team of 27 TNG colleages set a new record of 2h 09min 54sec for the construction of the largest Lego set ever produced.

The attained frequency of just under one brick per second was achieved with careful planning. The "Product Owner" created a dependency graph over all 17 packets of the set and, based on that, created stories to be worked on independently by the building teams during the Legothon. Retrospectives and a review process reduced the error rate still further.

The current best time of 6:18:15 was reduced by almost two thirds, although with an unlimited team size.
