Summary
🤩
Rockstar🎓
Top SchoolPaul Dreik is a Senior C++ consultant with 13+ years of hands-on experience building high-performance, cross-platform systems and improving code quality through static analysis, sanitizers, fuzzing and CI automation. Based in Stockholm, he combines deep expertise in mathematical programming (filtering, optimization, graphs) and multicore performance with practical security work—contributing fuzzers and hardening tests for prominent projects like simdjson, curl and OSS-Fuzz. He prefers Linux-centric development, but brings pragmatic multi-language skills (C, C#, Python, Matlab/Octave, PHP, shell) to select the right tool for each task. As founder of a long-running consultancy, he pairs production engineering with robust QA practices, from unit tests to packaging and cross-compilation. Notably, his open-source contributions have uncovered UB and overflow issues and integrated fuzzing into CI for widely used libraries, improving reliability at scale.
