Back to original languageAbout Holger
I am a graduate mathematician and experienced C++ developer with over 20 years of project experience in software and system development on Linux and Unix.
I support companies in modernizing legacy systems, migrating to modern Linux environments, as well as in C++ refactoring, performance tuning, and build system automation.
I work agile and test-driven (TDD, BDD), deliver maintainable, robust code, and help teams optimize their C++ development processes.
