Professional Work

Kleine Zeitung

Built a replacement weather page which would save the company around 120 000€ per year
- The new system is independent of the database, http framework and weather data provider. Which was important because the reason for redoing the weather page in the first place was a dependency of the old system on a 10 000€ per month database subscription.
Integrated a new comment moderation system for kleinezeitung.at
