Rockstar🎓
Top SchoolFrank Rehwinkel is a seasoned backend and systems engineer with over 25 years of experience spanning Bell Labs, router firmware at Ericsson, and startup-scale systems, now focused on Rust and AI tooling. He combines deep OS- and network-level expertise—demonstrated by contributions to Rust's io_uring runtime (tokio-uring) and miri/epoll tooling—with a pragmatic focus on testing, reliability, and secure transports. Frank has driven fast-path and control-plane router architecture as a principal engineer and now maintains production-grade async I/O components used widely in the Rust ecosystem. Comfortable across firmware, drivers, and high-level components like WebAssembly and AI-collaborative tools, he brings a rare blend of low-level systems insight and modern language/tooling fluency. Based in New Jersey, he is available immediately for remote opportunities.
