Summary
👤
Senior🎓
Top SchoolPeter Sommerlad is a seasoned software engineer, educator, and consultant with over two decades of experience specializing in modern, safe C++ and software engineering practices. Formerly a professor and director of the Institute for Software at HSR Rapperswil, he co-authored foundational works like POSA and Security Patterns and still influences C++ through ISO standardization and MISRA C++ guideline work. He now runs a consultancy focused on training, code reviews, and pragmatic refactoring to "rid the world of bad software," bringing academic rigor to real-world systems. A frequent conference speaker and contributor to community wisdom (including 97 Things Every Programmer Should Know), he combines pattern-driven design with unit testing and tooling for agile C++ development. Unusually for an academic, he also has a track record of production engineering—building early internet banking infrastructure and long-lived single-sign-on systems in C++. Based in Zurich, he blends hands-on coding, teaching, and standards work to help teams simplify and harden complex software.
