Rockstar🎓
Top SchoolJohnathan Van Why is a senior software engineer with 13 years of experience specializing in C++ and Rust for embedded, security-critical, and hard real-time systems. Based in Corvallis, Oregon, he has driven distributed backend development and operational ownership at Google while also contributing as a core member of the Tock embedded OS project, including implementing low-level debugging, modernizing Rust userspace, and authoring Tock's threat model. His work bridges firmware to cloud: designing test infrastructure and hardware drivers for OpenTitan and improving Rust language support for embedded use cases. Comfortable with on-call responsibilities and system-level design tradeoffs, he brings both hands-on low-level coding and system security expertise. An early robotics researcher, he applies practical real-time control and hardware-debugging instincts to robust, auditable software for constrained devices.
