Hi, it's QuarticCat

Sometimes I write my own things:

  • detypify: Typst symbol classifier
  • paguroidea: A reimplementation of the Flap parser in Rust

Sometimes I make FOSS projects faster:

  • difftastic (#393, #395, #401, blog)
    A bunch of optimizations, boosting it by 4x. (partially merged tho)
  • lalrpop (#814)
    Rewrite the lexer, making the whole parsing process to be 2x~30x faster.
  • exllama (#275)
    Optimize the hottest CUDA kernel, resulting in 20% speedup on 2070S and 10% speedup on 3090. (note it's already well optimized)

Interests

  • High Performance Computing
