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 https://zenbrowser.zeiss.com/zdb.
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.
Real Cost of Working Time
We want to show here, what the real cost of every productive working hour is, for an employee in the software development (in Germany). First we will calculate the number of working days and hours per year:
The calculation of the productive working time is based on the summary done by Billomat.
| Days | Kind |
|---|---|
| 356 | Total |
| 104 | Weekend |
| 8 | Holidays |
| 30 | Locations |
| 10 | Sick |
| 4 | Training |
| 156 | Total off |
| 200 | Work |
| 150 | 75% Productive |
Cost per Working Hour
On this basis, we then calculate the effective cost per working hour (presence / effective) for the gross salary and the total cost, respectively. (Numbers based on the PDF from 2013, s.b.)
All in all, one has to calculate with about 78 EURO per hour.
| Tage | h | h/J | EUR/J | EUR/h |
|---|---|---|---|---|
| 200 | 8 | 1600 | 69.900 | 43,69 |
| 150 | 8 | 1200 | 69.900 | 58,25 |
| 200 | 8 | 1600 | 93.450 | 58.41 |
| 150 | 8 | 1200 | 93.450 | 77.88 |
