      I worked on an „Internet of Things” prototype project. I was involved in every part of the development. I programmed microcontrollers, designed the MQTT-messaging based architecture, and developed a web plugin for Kibana. This project is mostly written in Python.

      I created a code coverage tool for C++. It performs better in a multi-core environment than Gcov by
      eliminating „False sharing”. It supports Linux and a special internal platform. With this tool the testers can measure the…

      I created a code coverage tool for C++. It performs better in a multi-core environment than Gcov by
      eliminating „False sharing”. It supports Linux and a special internal platform. With this tool the testers can measure the code coverage per test case for a whole cluster. This data can be used for coverage-based automatic test selection.

      I worked on a code comprehension tool. We used the LLVM/Clang infrastructure to statically analyse source code and persist the AST of it to a SQL database. We also developed a web frontend and backend to make the parsed source code available for the developers. It is like an IDE that runs in a browser. The name of the tool is CodeCompass, and it became open source on GitHub:

      I worked on a distributed database system. I was involved in design maintenance and code
      refactoring. I learned modern C++ programming and how distributed systems work.

  • Visualization of C++ Template Metaprograms

    Tenth IEEE International Working Conference on Source Code Analysis and Manipulation

    Template metaprograms have become an essential part of today's C++ programs: with proper template definitions we can force the C++ compiler to execute algorithms at compilation time. Among the application areas of template metaprograms are the expression templates, static interface checking, code optimization with adaptation, language embedding and active libraries. Despite all of its already proven benefits and numerous successful applications there are surprisingly few tools for creating…

    Template metaprograms have become an essential part of today's C++ programs: with proper template definitions we can force the C++ compiler to execute algorithms at compilation time. Among the application areas of template metaprograms are the expression templates, static interface checking, code optimization with adaptation, language embedding and active libraries. Despite all of its already proven benefits and numerous successful applications there are surprisingly few tools for creating, supporting, and analyzing C++ template metaprograms. As metaprograms are executed at compilation time they are even harder to understand. In this paper we present a code visualization tool, which is utilizing Tem plight, our previously developed C++ template metaprogram debugger. Using the tool it is possible to visualize the instantiation chain of C++ templates and follow the execution of metaprograms. Various presentation layers, filtering of template instances and step-by-step replay of the instantiations are supported. Our tool can help to test, optimize, maintain C++ template metaprograms, and can enhance their acceptance in the software industry.
