SEEKING WORK | Netherlands | REMOTE ONLY I find bugs and vulnerabilities in source code. This is my exclusive focus. - Strong focus on fuzzing - Integration into OSS-Fuzz or other fuzzing services for durable protection - Specialized in C/C++ but demonstrable experience in finding Java/JavaScript/Go/Objective-C bugs - Dozens of memory safety bugs in mature C/C++ code bases is not uncommon - Other types of bugs: denial-of-service, serialization asymmetry, spec non-conformity, path traversal, ... Proprietary code OK, NDA OK, background check OK, payment in crypto OK.
