Rockstar🎓
Top SchoolRyan Butler is a software engineer with 13 years of experience specializing in Rust, realtime systems, and virtual reality who currently builds secure hardware and system tooling in New York. He has shipped low-level Rust for TrustZone/OP-TEE, implemented a 150x reduction in OTA update sizes, and owns the company’s NixOS hardware-in-loop tester and CI/tooling. Ryan is a prolific open-source maintainer—authoring firmware and a realtime Flatbuffers/WebSocket protocol for SlimeVR and contributing to prominent projects like zmq.rs and WaveRNN to improve cross-device and multi-GPU support. His work blends systems engineering, secure enclave development, and realtime multimedia (gstreamer, WebTransport), and he’s comfortable navigating legal and security tradeoffs when open-sourcing company code. Notably, he created safe Rust <-> C# interop for Unity and has a track record of squeezing large performance gains (e.g., 750x in a Samsung pipeline) through careful low-level optimization.
