Meet the engineer - Jørgen Kvalsvik

Experience

Jørgen’s last job before starting patch was compiler engineering and toolchain development at Woven by Toyota in Tokyo, Japan from 2021 through 2023. In Tokyo he designed compiler features for strict safety requirements, and created robust and reproducible builds and bootstraps for compilers, linkers, assemblers, and other binutils. He also did C standard library sanitizers. Before joining Woven by Toyota he spent over half a decade writing programs at Equinor in Bergen, with a particular focus on seismic. At Equinor, he authored the popular open source packages segyio and dlisio, several in-house projects, and functioned as the techincal lead for his team.
