~LunNova

I'm Luna! Nice to meet you. Focus areas: ROCm in nixpkgs · Linux GPU everything · NixOS · Rust · Java bytecode horrors

A better future is fundamentally possible and worth striving for.
Give some of your money to effective charities if you're well off!

I will demonstrably maintain an entire machine learning ecosystem if that's what it takes to use my local training cluster.

If you're interested in hiring me for a US remote or west coast hybrid position, contact me at jobs26@lunnova.dev.
I'm particularly interested in ML & Nix, generally open to opportunities with a good mission statement.

Having room for growth as an IC is important to me. Technical leadership rather than formal people management.
