- The Dialer was connected to a HiPath ProCenter and this to a HiPath 4000 PBX.
- A CreaLog IVR was used for outbound dialing, touchtone and voice recognition.
- The Dialer server communicated with the ProCenter, the IVR and the agents.
- Besides the Dialer server, three client applications where developed:
- Agent Desktop, Campaign Control and Campaign Manager.
- The Dialer Manager is used to manage campaigns, timing factors, dialing strategies and phone number lists.
- Within the CreaLog IVR, scripts like the above can control the interaction with the called person or answering machine.
- The Dialer controller can be used by administrators to start and stop campaigns.
- Besides that, it can adjust the dialing mode and the campaign pace.

Code- and Schema Generator for .NET
This generator was developed across multiple projects. It is used to generate databases, database schemes, database tables as well as XSD files, corresponding typed datasets and source code to access the database or dataset.
- Based on the meta data table, the following structures will be generated: - database schema; all tables, indexes and constraints. - XML schema (XSD); all tables, indexes and constraints. - graphical representation of the data model. - documentation of the data structures.
- Besides that substantial C# code can be generated which wraps and manages the data structures. This code consists of based classes, thread-safe data classes and thread-safe collections of based classes. The code contains generated SQL statements to insert, change, delete or query the database, taking into account the primary keys, constraints and timestamps.
- Optionally the Generator can generate SQL code and wrapper classes for ADO.NET and .NET DataSets.
- The basic approach of the generator is similar to the Model Driven Architecture (MDA); but without its disadvantages especially in combination with complex algorithms.
- It performs a kind of object-relationship-mapping (ORM) but with a very low runtime overhead, because the necessary logic has been generated in advance.

1999 through 2002
- Cobasoft Clock 3.0 is a nice and compact time management tool. It can show multiple digital or analog clock control panels, and it has a sharp analog clock in the Windows taskbar. Timers and alarms can be set with only 2 mouse clicks. The Cobasoft Clock keeps an automatic activitiy log, supports simple project billing, and shows the moon phase.
- The Cobasoft Clock is fully world-time enabled. It can show analog or digital clocks for different time zones, with customizable name and daylight time saving options. Alarms and Timers can be set relative to the time zone of one clock; this can be handy when travelling or when calling relatives in other time zones.
- The Cobasoft Clock is used by self-employed and home-office workers to track their working time automatically. It runs in the background and writes a report of the currently open window and the time spent in it. Additionally, one can choose a current project manually. This is also logged in the report and its times are accumulated. The automatic tracking can be turned off. The Clock can also be switched to Private mode, making it invisible for other users of the computer.
- The Cobasoft Clock is distinguished by the fast and easy way to set alarms or timers - one just takes a marker and drags it to a time, that's all. The alarms and timers can also launch programs and play sound and video files. They can be limited to certain days of the week.
- The moon phase icon is shown in the task bar, too, and has a tooltip that shows the exact moon age and time of the next full or new moon.
POET-EA - Electronic Document Management, HypoVereinsbank AG, Munich.
April 1997 until March 2000
- My task was the development of an Electronic Document Management system for the real estate department of a big bank. This system integrated scanned documents, existing office documents (WinWord, Excel...) with customer and account information.
- We used WANG and KOFAX imaging software and professional document scanners from Fujitsu and HP.
- Initially I developed requirements and design in close contact with our customers; the EDP and specialist departments. We developed specifications and prototypes.
- We mastered the year 2000 conversion and the fusion with Hypo Bank.
- My main task were the development of the user interface, the coordination of the team programmers, the development and assignment of their work packages, some part of the version management and some installation and rollout coordination.
- The project used Documentum and IBM VisualInfo as document storage and Microsoft SQL Server as database.
- Microsoft Outlook and Exchange served were used for the workflow implementation.
- I developed a business objects design which served us very well and which survived some very encompassing restructurings. It proved as indispensable for successful maintenance of the software.
This image shows a tree view of all accounts of a single customer. Under each account it shows the documents, grouped by document categories. Below the tree is a window with overview information for the selected object. On the right hand side, the details of the selected object are shown; for example a scanned image.
This image shows the scanning application. It was optimized for easy and efficient usage and allowed direct control of a variety of connected professional image scanners.
