The cornerstones of programming are still programs based on Windows and increasingly on Java. Dupp GmbH has been awarded as a Microsoft Partner through the further training of its employees and the certification of its own programs. Redmond (USA) awards the highest status partner classification to Dupp, which has been a “Microsoft Gold and Silver Partner” for years. Not many IT companies received this highest award. Microsoft partners are considered the most experienced partners in their specific field. Partner status requires a certain number of certified software products and proven excellent expertise in certain fields of competence. Only companies that meet the highest customer service requirements, have proven their expertise and successfully passed an intensive certification process are appointed Microsoft Certified Partner. The program helps identify customers and companies that have successfully proven their experience with Microsoft products and technologies.

The still very small shop is now finally closed and the space is needed for the constantly growing staff for service and programming.
