Summary
🤩
RockstarRyan Hileman is a founder and seasoned software engineer based in the San Francisco Bay Area with 18 years of experience building low-level systems, emulation, and developer tools. He brings deep backend expertise in systems programming—kernel-like syscall work, emulators (Unicorn), and platform emulation/userland projects—paired with practical contributions to language bindings and tooling in Go, Rust, and Python. His open-source footprint includes enhancing an iOS Linux shell, contributing crypto bindings for OpenSSL in Go, and hardening Tree-sitter and GUI integrations, showing fluency across OS internals to UI/web compatibility. As a consultant-turned-founder since 2017, he combines hands-on implementation with product instincts, often tackling tricky memory, concurrency, and cross-platform interoperability problems. Notably, his work on syscall handling, futex timeouts, and emulator regression tests reflects a focus on correctness and reproducible behavior in complex, architecture-spanning systems.
