nix config
nix-darwin + NixOS config for a box at home that I use to write code and watch movies/anime.
hi, i'm xavi
HEY, i'm a cs student that really likes playing with computers (including video games), and this is my wip website. I'm in the process of changing the site to be more personal.
I like systems programming. This summer, I interned at Cloudflare in Austin.
Last summer, I worked on the Pyrefly (a Python static type checker and LSP) team at Meta in NYC, shipping notebook support.
Before that, I interned at Datadog, working on user onboarding for the web platform, and Caseware, rewriting monorepo dependency resolution to bring down CI times.

View on GitHub ↗low-overhead macOS system monitor for Apple Silicon, with a Rust backend built on Mach, AppleSMC, and IOReport, plus a native Swift/AppKit frontend.
my use case is spotting random runaway processes pinning a CPU core, and I wanted something lighter than btop and Stats.
this averages ~0.05% CPU (per-core)(trying to bring this lower…) over a 30-second profile. I use Nix and mini benchmarks to track overhead as I add stuff I want.
