Rockstar🎓
Top SchoolChristian Blichmann is a Senior Software Engineer based in Zurich with 11 years of professional experience focused on binary analysis, sandboxing, and security tooling. At Google he maintains BinDiff and works on sandboxed APIs, bringing deep C/C++ expertise to hardening and isolation of native code. A long-time open-source contributor, he helped bootstrap Google's BinExport format and improved widely used projects like YARA and Binary Ninja's API, showing skill across build systems, lexer/parser work, and cross-repo syncing. His background at zynamics and Google gives him rare domain knowledge in reverse engineering and threat intelligence combined with pragmatic DevOps and build-system improvements. Beyond code, he tends to the plumbing that keeps security tooling reliable—build files, sandboxes, and small portability fixes that quietly unlock larger engineering productivity gains.
