Rockstar🎓
Top SchoolWalter Karas is a veteran software engineer with over three decades of systems and embedded C/C++ experience and nine years focused on modern C++17 backend work, most recently contributing to the widely used Apache Traffic Server. Comfortable across low-level firmware, network dataplanes, drivers and high-level server code, he favors new development and modular, maintainable designs—illustrated by small open-source projects (C++ bitfields, intrusive container templates) and a modular C++ chess program. At Yahoo he delivered measurable improvements (e.g., >10x trace overhead reduction) and added practical features like HTTP/TLS metrics and ALB-integrated cert checks. Now semi-retired and selectively available for open-source collaboration, he seeks code-focused peers who will critique his innovations and point him to interesting projects. A less obvious strength is his long habit of building reusable, formalized class templates and simulation tools that bridge hardware behaviors and host-side software.
