You love building cool robot applications, tackling complex navigation challenges, and making hardware *do things*.

Benefits: • Perfect reproducibility across all devs and CI • OS independence (Fedora, Arch, Ubuntu/Debian, NixOS) • Lightning-fast caching • Simple activation (just cd into project) • Native performance (no Docker overhead)
