I write things that people will use. C, C++ and Rust are my preferred languages; JavaScript and Python are the ones I use most and know best. Currently in university.
I'm open to collaboration and contributions.
Everything below is built and maintained in my free time.
A multipurpose Discord bot running as a sharded fleet with one supervising manager process and N cluster processes. Backend uses MongoDB.
Uses: Node.js v24+, discord.js v14, MongoDB (Mongoose), discord-hybrid-sharding, discord-player (custom fork), node-canvas, ffmpeg, tesseract-ocr.
- 210,000+ users
- 188 commands, 58 event handlers
- ~120,000 lines across 434 source files, with 1,124 commits since September 2021
- Diff-based document storage, multi-process DB workers, local caching
- OCR-backed and perceptual-hash scam detection on posted images
- Cross-server role sync, ban appeals and synced moderation over a credential-less handshake
- Hot reload, rolling restarts andclass patching
- Shard, network and file watchdogs
The Raspberry Pi runs Void and hosts: the Relaxy! bot, CDN, website, dashboard and health/monitoring services + a few self-correction scripts.
All services are isolated using Podman and bubblewrap.

Web dashboard for the bot. Discord OAuth login, three access tiers computed from the OAuth guilds permission bitfield. Has per-user profile customization as well.
Uses: Fastify, custom MongoDB driver, JavaScript, esbuild.
- ~43,000 lines across 55 files
- Discord OAuth-based access control with three permission tiers, per-request authorization checks, per-session CSRF protection, and an explicit allow-list of fields that can be modified.
Node library that generates Google Emoji Kitchen combination image URLs from two emojis.
Uses: JavaScript, webpack (CJS and ESM builds), TypeScript, python3.
- 122,000+ total downloads (npm-stat)
- 1,221 dependent repositories on GitHub
- 619 base emojis, 330,640 valid combinations
- Compatibility data compressed into two lookup tables (codepoints and release dates), so each entry is a two-integer pair instead of a repeated string

Runtime introspection logger for Python. Reports variable assignments, mutations and function calls as they happen, with no debugger and no instrumentation of the target code beyond a decorator.
Uses: Python 3.10+, sys.settrace introspection.
- 8,000+ PyPI downloads
- ~3,300 lines across 11 modules, 14 test modules
- Educational mode rewrites output into plain sentences for teaching
- Tracks locals, attribute writes, container mutations, arguments and return values

- relaxy-website (HTML, CSS, vanilla JS) - Static site with no dependencies and no build step. 12 pages, ~5,400 lines of JS, ~4,500 lines of CSS, plus a separate uptime page.
- tracker (Python) - CLI project tracker with Git repo discovery, search/filtering, bulk editing, configurable output, and a background update daemon.
- abba (C++26) - Arbitrary Binary Behavioural Anticheat. Memory scanning, file integrity hashing and INI-driven configuration. Still in the early stages.
- von-neumann-machine-simulator (Rust, egui/eframe) - Von Neumann architecture simulator with a native GUI.
- ibus-mozc-system (Shell, X11) - Scripts and config that make Japanese input under IBus and Mozc work on a keyboard without dedicated JP keys. The entire thing constantly monitors itself to make sure nothing breaks.
- neural-network (C++26) - Multithreaded neural network written from scratch.
- raytracer (C++) - Ray tracer following Ray Tracing in One Weekend.
- hprint (C++26) - Header-only utility for centered terminal headers with compile-time border characters and terminal width detection.
- path-variable-editor (Python) - Windows PATH editor that works past the 2047 character limit.
