Core Topic since 2012
- Company specific develeoper trainings with a special focus on transitioning an existing code base from C to C++ (some extending into consulting and coaching contracts under an NDA)
Selected Projects from 40+Years
- Participating in the Redesign of a Bio-Medical Device in a team of twelve (2010 - 2011)
- Improving a Tcl/Tk-based Prototype of a Control Unit for Handling Robots in a team of two (2009)
- Designing and implementing a set of Tools for Tcl/Tk-based Software-Development in Embedded Linux (2009)
- Realizing a Tiny Framework for Performance Evaluations of C/C++ Code fragments (2008)
- Designing and Implementing a Web-based Backend for FlexeLint (2007)
- Working as C++-Coach for an International Project in a team of several hundred (2004 - 2007)
- Reviewing an Robotics Gripper Arm Control Algorithm written in C followed by a C++ re-implementation with extensions in a team of four (2003)
- Implementing a Pin-File-Editor for easier input and validation of chip specifications in Tcl/Tk (2001)
- Designing and building a Centronics Interface for a Paper Tape Punch (1985)
- Implementing a Multi-User Inventory Control System for UniFLEX (1982 - 1984) and a successor for Xenix and Unix System V (1986 - 1987)
- Participating in various Industry Solutions based on the IBM 5110 single user computer (1979 - 1981)
- Designing and building a Modular Measuring System for experiments at the Hochspannungs-Institut (High Voltage Department) of TH-Darmstadt (1980)
- Redesigning the "Analogue Computer Experiment" at the Institut für Messtechnik (Measuring Technique Department) of TH-Darmstadt (1978)

- Building a Serial Arithmetic Unit from Simulog components (1971)
There are no projects worth mentioning between 1988 and 2000 as during that stretch of time my work was mostly centered on giving trainings.
