A follow up project of prior project (see two below). Advantest – a former HP company – has contract manufactures, who produce Advantest hardware worldwide on demand. FTS is a custom quality tracking and management system for that.

Tasks:

• Create and implement an new “Industry 4.0” / M2M (more) automated solution
• Create a new user interface
• Neat-less transition from existing solution (several Gigabytes of data every day all over the world, very huge data base)

Bosch with the “Bosch Internet of Things Cloud” participates in the emerging IoT market with the potential to become a key player.

Tasks:

• Evaluate application protocols in regard to: vehicle-to-server-, serverto-server- and server-to-browser-communication, (massive) real time data transfer and ease of implementation
• Evaluate embedded Linux IPC (Inter Process Communication) methods and technologies regarding ease of implementation and “when to use”
• Evaluate existing internal and public available frameworks (e.g. OsGI, OMA)
• Propose a embedded target architecture to abstract from huge variety of vehicle network specifics
• Propose client-server architecture with regard to: target possibly in field over years, different high level solutions (e.g. car rental fleet, test fleet,private owned)
• Moderate a weekly meeting to discuss and develop further above items, know how transfer with Bosch software engineers and architects

Advantest – a former HP company – has contract manufactures, who produce Advantest hardware worldwide on demand. FTS is a custom quality tracking and management system for that. It originated in 2001. There have been three changes of the development team and lead. The project has been maintained by
a third party in the U.S. The customer now wants to regather the application knowledge and regain full control.

Tasks:

• Re-engineer the system from the ground and re-create project documentation (class diagrams, use cases, sequence diagrams, database diagrams, requirements)
• Assist with current development and software development processes
• Ensure project to be runnable and maintainable for the next few years

Result:

• 10.000 lines of unused code removed (1/3)
• redesigned architecture leading to much lower maintenance costs

Ulixes robot systems are automation robots with conveyors and grapplers e.g.used for industrial automated packaging.
The Ulixes basic system is a distributed system with a custom application protocol based on TCP/IP. The system however is quite old and written in an outdated programming language.

Tasks:

• Reprogram the system from the ground with .NET C# 4.5 (TCP Clients, TCP Servers)
• Create custom framework to easily create Ulixes robot apps
• Planning, designing and implementing according to the customer

Planning, design and implementation according to the customer.
The corresponding webserver was also implemented by me: ulixes Webserver.

Ulixes robot systems are automation robots with conveyors and grapplers e.g. used for industrial automated packaging.
This project added an HTTP access web-api to the existing robot system (actorsand sensor-system):

• starting / stopping the system via HTTP
• client-events like e.g. new object on conveyor
• system status (running/stopped etc., number and position of objects on conveyor, ...)

Tasks:

• Planning, designing and implementing according to the customer. Please also have a look at the associated HTML5 UI project: ulixes WebUI.

“openAbk” has been created in a consortium of the companies BMW, EmbusSys, Ceatec and G.i.N. It is a manufacturer overarching CAN-TO-HTTP interface for displaying real time data measurement values and data logger interoperability.
G.i.N. brought a big piece of the cake by revealing their existing CAN-TO-HTTP interface from their “G.i.N. Logger Webserver” project (this project has also been realized by myself, see further down).

Objectives:

• interchangeable displays and data loggers among different
  manufacturers
• common display of real-time data
• common administrative data logger user interfaces

Tasks:

• gathering requirements in accordance to all members of the
  consortium
• implementation
• ongoing development in accordance to all members of the consortium

G.i.N. data logger generically collect data from CAN (and other) bus systems. “Edson” is part of a global internet-available data base from Audi AG. Within this database can store measurement data usually via mobile transmission. These transmitted data is then available for further usage either by Audi employees or
by automatic software processes. Examples which do use the Edson data base are Audi's car-sharing and electric vehicles fleets. The security requirements of the Audi AG server have been extra ordinary challenging.

Objectives:

• G.i.N. data logger shall transmit measurement data to Edson server via UMTS
• G.i.N. data logger shall receive new measurement tasks via the Edson server

Tasks:

• gathering customer's requirements
• planning, design, implementation, test
• support and ongoing development according to customer's needs

This project has been brought to the attention of the VW executive board (during a semiannual presentation of interesting new developments). The TU Ingolstadt picked up on the development in a bachelor thesis. BMW and Daimler use a sibling of this project (called “openAbk”), which has also been implemented by myself (see above). G.i.N. data logger generically collect data from CAN (and other) bus systems. A new feature of G.i.N. data logger is to send real-time measurement data from bus systems via HTTP. Another new feature is administrative access via HTTP, too
(this project called “GLWebserver” has also been implemented by myself, see project experiences C++ above).
„GLWebDisplay“ is the corresponding user interface within the web browser offering following functionality to the end user:

• informative and administrative access to the data logger (like e.g. known from a “Fritz Box”)
• View of predefined bus signals in real-time (< 100 ms) in tables and charts

Tasks:

• design of use cases
• design, implementation and test

The company G.i.N. has been looking for a modern project management tool with two main requirements: 1. Support for management in project tracking 2. support for developers in daily work-flow.
In case of the developers this lead to a collaborative ticket based tool. The management needed a quick overview over the overall project status and wanted among other things to have the impact of changes immanent.
Tasks:

• Creation of decision matrix
• Evaluation of several tools

I have been entrusted with the task of evaluating the situation of all development projects with help of MS Project.
The company G.i.N. knew three kinds of projects: software development projects, embedded software projects and hardware projects with possible dependencies among all projects. In addition all employees were involved in several projects.
Tasks:

• Capture and tracking of existing projects work modules in consultation with the coworkers
• Gathering work load of each coworker
• Create overview with MS Project / Gantt charts

Objectives:

• Visualize project durations and resource dependencies
• Visualize inter project dependencies

This project has been brought to the attention of the VW executive board (during a semiannual presentation of interesting new developments). The TU Ingolstadt picked up on the development in a bachelor thesis. BMW and Daimler use a sibling of this project (called “openAbk”), which has also been implemented by myself (see above). G.i.N. data logger generically collect data from CAN (and other) bus systems. “GLWebserver“ is a HTTP interface for G.i.N. data loggers allowing for following functions:

• information about data logger (current measurement, duration,
  firmware version, ...)
• administrative access (e.g. setup of wireless network)
• Create, retrieve, update and delete of arbitrary data.

But the most stunning feature is the CAN-TO-HTTP interface allowing real-time measurement data completely within the HTTP protocol by leveraging a HTTP Long Polling technique.
Tasks:

• gathering customer's requirements
• planing, design, implement, test
• support and ongoing development according to customer's needs I have implemented the corresponding user interface in the project “G.i.N. Logger WebDisplay”

G.i.N. data logger generically collect data from CAN (and other) bus systems. They are widely used in vehicle continuous tests at major car manufacturers. A special use case is the logging of classification data for example “motor temperature greater then 90° and speed lower 160 km/h occurs 2.5% of overall
test time“). With the help of “Class View 2” the user can select form test vehicle, test drives (= time span) and there recorded classifications. From this selection MS Excel reports are created included charts. The automatically created output can be mixed with arbitrary user input in MS Excel thus creating test drive
reports. Once created test drive reports can be reused with the automatic content updated while leaving the manual parts unchanged. It is in particular notable that the customer has terabytes (!) of collected in a file system and collects hundreds of megabytes each day. It has been a challenging task to
create a user interface which were appealing and responsive at the same time.
Tasks:

• gather requirements from the customer
• planing, design and implementation
• test
• support and ongoing development for the customer

The Helaba is the federal bank of the federal states Hesse and Thuringia. The department "Verbundbank" looks after around 250 "Sparkassen" (these are regional federal owned banks), with tendency to rise. The department gets an unique aggregation of business data of the 250 Sparkassen from several sources.
These information is used for controlling, sales and the upper management. An existing VB.NET application (build for 40 banks) supported the department in collecting and archiving manually from excel sheets. At the same time it created business reports.
The VB.NET application was reaching its limit. At the same time an automaticdata aggregation was desired. Thus a new .NET application was created.
Task:

• gathering the customer's requirements
• planing, design, implementation and test of the software components (database, MS Excel import and export, user interfaces)
• support and ongoing development

The “Finanz Informatik” is the central IT service provider for the German
Sparkasse group (a nationwide federal owned bank). The project “Internet
Branch” bundles all development concerning the online appearance of all
Sparkassen banks.
This includes online banking, online product sells or customer information
offers. At the same time it is a content-management-system, allowing the
different Sparkassen banks (there are around 420) e.g. individual style, starting
page and advertisement.
Last but not least there are interfaces to other system of the Sparkassen group
(e.g. marketing systems: automatic notifications of customer service
representatives.)
Tasks:
· enhancements (new user masks, ...)
· technical consultancy for the banking departments, support at writing
specifications
· debugging
· Design, realization and coordinating of a component for partner web
applications (like credit card or stock exchange applications). This
included single-sign-on (no second user logging at partner application
required) and keep-alive (user is not automatically logged out while
active with partner application). Because some of the user data was
transferred via the web to the partner applications and the solution
concerned session handling there was a high need for security

In a three years project Zühlke developed an integrated solution reaching from control units up to a web portal in order to offer a most professional fleet management for customers of a wheel loader manufacturer. Part of the web portal and my responsibility was a reporting component. Within the report component you can view different kind of processed data in form of tables and diagrams. The shown data concerns the fleet (e.g. fuel
consumption, operation schedule, maintenance overview, machine log) or information about the web portal itself (e.g. number of registered machines, workload over time).
Tasks:

• Design and implementation upon given feature specifications
  (database, backend and fronted, vertical cut)
• tests

My first project at Zühlke aimed at developing an usability prototype for machine displays (touch screens). The customer was a manufacturer for wood processing machines. An additional user interface design company delivered exact specifications concerning the layout. In this project it was in particular challenging to deliver within the agreed short time.
Tasks:

• Exact and fast implementation of parts of the prototype according to the specifications

It was my assignment to maintain and develop further an existing software product for test process automation (TPA). Among other tasks I did a complete re-engineering of the software.
Tasks:

• Rework / development of test process automation (TPA) software
• Rework / development of an editor
• Maintain interface of TPA-software with test management tools

My diploma thesis was a cooperation of University of Paderborn and dSPACE GmbH. It aimed at developing a common proceeding for implementing automated checks for any given model guideline. For realization of automated checks two languages were considered: MATLAB’s m scripts and a model based approach. The model based approach was evaluated concerning its industrial practice. In addition I implemented a Java-MATLAB adapter to realize the model based approach.

Tasks:

• Searching and classifying of existing model guidelines (MAAB, TargetLink)
• Implementation and analysis of archetypical guidelines in MATLAB m and in the model based language
• Evaluation of the model based language concerning its industrial practice
• Implementation of a Java-MATLAB adapter to realize the model based approach with Simulink models

Results:

• Working Java-MATLAB adapter
• Model based approach in principal convenient, but current technical realization not practical due to immense run time problems

Together with a second student assistant we developed a
documentation-/requirement-tool (SPICE, ISO/IEC 15504) for internal use in Visual Studio 2005 using C# and XML/XSLT.
After talking to our team leader we independently designed and developed thesolution (including GUI-design). After the release our job was to maintain and to develop the tool further and to provide support.

Objectives:

• Tracking of requirements down to implementations
• Mapping of employees to requirements and implementations

Tasks:

• design and implementation upon consultation with the softwarearchitect in charge
• tests

Results:
At the time I left the company the tool was used by around 100
employees and developed further by another student assistant

My bachelor thesis summed the technical results of a cooperation between the chair of “Planning and Logistics” (Business Information Systems) and the Siemens Demantics AG, Nuremberg, up. The work was done by me and two of
my student colleagues. The Demantics AG was looking for a solution which was able to transfer data from a Siemens Demantics’ ERP-system to a SAP-system while in operation. For a correct transfer it was partly necessary to transform the structure of the data (e.g. DD/MM/YYYY to MM/DD/YYYY).
In addition a visual editor was required in order to define the data structure transformations in an intuitive visual way.
Tasks:

• Creation of a run-time environment which receives data from the ERPsystem, exports them to XML, transforms them using XSLT and finally imports the resulting XML file into the SAP-system
• Creation of a visual XSLT editor in order to define structural
  transformations
