A little about me

  • Zig-z Accelerated the Zig parser up to 3x πŸš€πŸš€πŸš€
    • ⚑ Zig is my personal favorite programming language
  • LLVM dragon-head logo Assembly auditor
    • Reduced the instruction count of must_be_2_3_continuation in simdutf/simdjson from 6 to 4 on x86-64 (with similarly small improvements on other architectures). Although this sounds trivial, this garnered a 4% performance uplift in utf8 validation!
  • πŸ“ƒ Invented a data structure [demo, paper] that improves upon prefix trees (i.e. tries) to solve the scored autocomplete problem orders of magnitude faster πŸš€πŸš€πŸš€πŸš€πŸš€
  • Co-Developed the initial version of roblox-ts with @Osyrisrblx
  • @RoStrap Created the RoStrap project
  • Lua My first programming language was Lua
  • Big-Theta connoisseur
    • Did you know that a priority queue implemented as a 1-2-3 Skip list can perform the extract-min operation in amortized constant time?
      • And yes, insertions are still logarithmic! And any other value can be extracted in logarithmic time!

Exciting new tech

  • Mill instruction set architecture
    • An in-order statically scheduled architecture that achieves the performance of an out-of-order superscalar with extremely innovative tricks
    • Eats loops like goats eat underwear
  • LuaJIT Remake
    • Automatically generates a blazingly fast interpreter and multi-level JIT compiler given only a semantic description of a language's bytecodes
  • Pijul version control system
    • Based on the theory of patches and not slow like DARCS
  • Bun JavaScript runtime
    • Blazingly fast runtime and toolkit for JavaScript
