Customers and References

In the following text we will give you a short overview of some of our most important customers and the projects we realized for them.

Carl Zeiss® Microscopy GmbH

We realized the product "ZEN browser", a web-based high-performance image and document database. Its main purposes are fast display of and fluent interaction with huge images, as they result from modern high-tech microscopes. The system may be used from desktop and mobile devices, without restrictions in functionality and independent of the client operating system (Windows®, OS X®, iOS®, Unix® or Android™). Metadata may be imported and used for all documents; import, layout and drill-down are fully customizable; images and their various labels and metadata may be arranged as required. The system is able to manage various image formats. Any type of document may be imported and managed. It contains version management and collaborative features. A demo may be found on

Automation Systems Company, Dresden

"...auf diesem Wege bedanken wir uns für die Durchführung der drei Workshops "Debugging" in unserem Haus. Die Workshops sind bei allen Teilnehmern sehr gut angekommen und werden uns in den laufenden und kommenden Projekten sehr weiterhelfen. Trotz der sehr knapp bemessenen Zeit unsererseits waren Sie in der Lage die fachlichen Informationen sehr gut an die Teilnehmer zu vermittein. Hervorzuheben ist auch die sehr gute Zusammenarbeit und die Kurzfristigkeit in der Sie die Workshops möglich gemacht haben."

Microsoft Germany GmbH

Karl Geitz been working as freelancer for Microsoft GTSC EMEA in Distributed Services for about 17 months. He worked in the Distributed Services section of the european Premier support organization. His topics were Windows Communication Foundation (WCF), SOAP and XML, Web- standards, web site security, troubleshooting and debugging and consulting. His colleagues were knowledgeable experts and very nice and interesting people. They solved problems of performance and stability for clients throughout Europe.

MTU Aero Engines GmbH

"Den Berater Herrn Karl Geitz hatten wir 2007 in der Entwicklung und Programmierung verschiedener Softwareprojekte eingesetzt, die in C# implementiert wurden. Es handelte sich sowohl um Server-Komponenten als auch um graphische Benutzeroberflächen von Clients.
Herrn Geitz können wir jederzeit weiter empfehlen, er hat stets sehr schnell und effektiv gearbeitet, die Entwicklungswerkzeuge sehr gut beherrscht und auf Grund seiner Erfahrung und seines Überblicks für alle aufgetretenen Probleme in kurzer Zeit erfolgreich und eigenständig eine Lösung gefunden. Hervor zu heben sind seine .Net- und SQL-Detailkenntnisse."

Siemens AG

Since many years we are working for Siemens AG, in the divisions traffic control, medical systems and telecommunications. (I&S ITS, MED DB, ICN bzw. COM).

We realized some sophisticated applications for Siemens. In the first four of the following projects I developed the architecture and was project lead.

  • COM: Code-and Schema Generator for .NET
  • COM: Dialer Server Applikation for HiPath ProCenter, .NET
  • COM: CRM Sales Support System, .NET.
  • MED: XML based generic testing system for SynGo.
  • I&S: CONCERT-NT - A traffic control center.

Cobasoft Advantages

Why should you award us a contract? Why should you work with us and trust us to implement large software systems? In the following we try to give some good arguments:

Choosing the Right Strategic Direction

By choosing the right strategic direction at the beginning of a project, substantial costs can be saved during development and after rollout. By choosing an appropriate architecture, by good design and by using an efficient software factory we support you.

Stability by Good Design

The design is the basement on which the development of a software must rest. Only if the underlying design is stable, complete and efficient, the application which is built upon this design, can be as stable, complete and efficient. The quality of the specifications determines the success of the project. Profit from our experience!

Refactoring and Porting

Programs grow old, too. The utilized technology goes out of fashion. The data structures no longer keep up with the current requirements. To get a handle on these problems, refactoring and porting are appropriate measures. We have much experience with these tasks and can speed up and ensure the implementation.

User Interface, Data structure, Algorithms

These are main pillars of every program. By finding the optimal pattern for each of these pillars the software development can be led to success. We evaluate or provide the quality of these components and find the matching solution for you.

Our Tariffs

Our tariffs depend on the kind of work, the required qualification and the planned duration of the task. Please ask us for a quote!
Our subsidiary on the Canary Islands allows us to provide services at good conditions. From there, very good air connections to the mainland and the British islands exit. We can reach every part of Europe quickly and a skilled and multilingual pool of manpower is available.
