Ole Ravnås
Security Researcher at The Frida Project – https://frida.re
Stavanger, Rogaland, Norway
Summary
🤩
RockstarOle Ravnås is a veteran security researcher and systems engineer with 26 years of experience building low-level tooling, reverse-engineering platforms, and cross‑platform dynamic instrumentation. As founder and long-time maintainer of Frida, he created a now widely-used dynamic binary instrumentation framework and continues to improve its core across platforms, including deep JVM and Android support. At NowSecure he applies that expertise to practical security research, while his open-source contributions span critical projects from GLib, libffi and Meson to Node.js, Capstone and Radare2—demonstrating strength in portability, concurrency and platform-specific debugging. He combines hands-on C/C++ and systems work with TypeScript and front-end polish (e.g., Frida website and DefinitelyTyped), and is comfortable shipping both tooling and polished UX. A less obvious facet: he’s repeatedly solved tricky platform and ABI edge cases (iOS/arm64e, Apple Silicon, MSVC peculiarities), making him a go-to engineer for cross‑platform correctness and instrumentation.
