Scouting report

C++ standards-track engineer with 362 merged PRs

assessed from open-source footprint

Principal
66signal

Johel is the standout specialist: a deep C++20 systems engineer who maintains his own JEGP libraries (CMake modules, a numbers/concepts library) and has 362 merged pull requests over a decade, even landing a commit in cplusplus/draft — the C++ standard text itself. Star counts are modest because this is library/infrastructure work, not consumer apps. A genuine fit for teams needing rigorous modern-C++, build systems, or standards-adjacent expertise.
