M1tsumi/README.md

Hey there! I'm M1tsumi

I build Discord libraries in languages you probably wouldn't expect. Most of my time is spent wrestling with Swift, Objective-C, Zig, and Rust - basically anything that compiles to something fast and doesn't make me want to throw my computer out the window.

Discord Docs

Stuff I'm Proud Of

These are the projects I pour most of my energy into:

Project What it does Why I built it
Arena-b Super-fast arena allocator for Rust with basically zero overhead Got tired of malloc being slow, so I built something faster
SwiftDisc Discord API wrapper for Swift - v10 support, async/await, cross-platform. Zero dependencies. Swift needed a proper Discord library that wasn't terrible
Jod Job management system that actually works Was frustrated with existing job schedulers, so I wrote my own
MobScaling Smart scaling for mobile apps Needed something better than just throwing more servers at problems

Other Discord Stuff

Project What it does
Caelum Objective-C version of a Discord library. Plays nice with Swift.
Zignal Discord library for Zig. 175 endpoints, 56 gateway events, voice support.

Systems & Tools

Project What it does
VelocityX Lock-free data structures for Rust - MPMC queues, concurrent hashmaps.
ZeroProto Zero-copy protobuf implementation.
AeroSocket Lightweight WebSocket library.

What I Use

What I'm Working On

Right now I'm mostly:

  • Keeping Discord libraries from breaking when Discord decides to change everything
  • Making VelocityX even faster (because fast is never fast enough)
  • Writing docs so people can actually use this stuff
  • Adding cool new features to Arena-b, SwiftDisc, Jod, and MobScaling
