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
• 192 commands, 58 event handlers
• 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
• One shared implementation behind every moderation action, for the usual moderation, dashboard as well as linked servers
• Hot reload, rolling restarts and class patching
• Shard, network and file watchdogs

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, the native MongoDB driver, JavaScript, esbuild.

• Discord OAuth-based access control with three permission tiers, per-request authorization checks, per-session CSRF protection and a strict list of modifiable fields

The bot's showcase site, plus the public uptime page. I've designed it from the ground up to be as fast as possible.

Uses: HTML, CSS, JavaScript.

• 12 pages, ~4,600 lines of JS, ~5,850 lines of CSS
• Changelog, devlog, technical writeup, CDN, Matrix and Minecraft pages
• The uptime page is driven by the health feeds published below

The scripts and services that ensure maximum possible uptime. Written for runit on Void.

Uses: Node.js, POSIX shell scripts, nftables, runit.

• Probes 24 services on a ten-second loop and publishes three JSON feeds (one full, one public, one status)
• Hardware watchdog that pets /dev/watchdog, so the Pi reboots automatically on a deadlock
• An uptime ledger with day buckets, incident detection and cause inference, mirrored into a Discord outages channel
• incident CLI tool for declaring and annotating outages
• Scripts to keep sshd at the top of the CPU, IO and OOM priority lists, with a self-contained nftables table putting SSH in band 0 at DSCP CS6 to ensure the Pi stays reachable while it is dying
• error pages generated from the dashboard's own CSS, so I don't have to write new ones by hand every time I change something

• Local AI Studio (Rust, ratatui) - Super+R popup for quick questions to local models. Shows timing per reply, has approval modes, and the model can look at the screen, read selected text, search files and search the web.

• g-mang-hud-mattfor-edition (TF2 HUD) - My modification of a 16+ year old TF2 HUD written in ReScript.
• .bashrc (Shell) - My .bashrc. System, packaging, media and programming utilities, each documented with what it needs installed.
• gtk-config (CSS) - My GTK 3 and 4 theme for Void.
• xfce4-notes-plugin (Vala) - Fork of the Xfce notes plugin: opens any folder of notes (every folder a window), works well with git and Syncthing, reads legacy encodings, scrolls between notes and shows/hides on a shortcut.

• university-coursework (C, C++, Python, Jupyter) - Everything from my Computer Science degree, organised by semester.
• neural-network (C++26) - Feedforward multithreaded neural network written from scratch, with a test suite. (also submitted as the final project for algorithms & data structures)
• visual-sorter-v2 (C++20, OpenGL [GLFW], SDL3 and ImGui) - Twelve sorting algorithms drawn one comparison at a time. Performance metrics, graphs and more.
• emergency-department (C++20, POSIX IPC) - A hospital emergency department where every role is a separate process, coordinating purely through message queues, shared memory, semaphores and signals. Final project for operating systems class.
• numerical-methods-labs (C++) - Numerical methods lab programs.
• university-dotnet (C#) - Every exercise from the .NET class.

• relaxy-public-v1 (JavaScript) - The first stripped-down showcase of the bot, from 2023. Superseded by relaxy-public-v2.
• grand-archives-discord-bot (JavaScript) - A bot for an old roleplay server. Its alchemy command is what emoji-mixer grew out of.
• escape-the-backrooms-teammaker (C++, Win32) - Team builder used by nightmare runners early in the game's life.
• matura-exam-preparation (Python) - Scripts and notes I used as study material for the Matura CS exam.
• asteroids-old (C++, SFML), c-sorting-visualiser (C) and backprop-neural-network-side-project (Python) - Early things from when I was first learning to program.

• autosplitter (ASL) - The LiveSplit autosplitter for the game, covering versions 5.0+. Auto start, splits on level transitions and cutscenes, load removal, and a paused timer in cutscenes, the main menu and on crashes. Based on uhara by ru-mii.
• UE4SS (C++) - Our fork of RE-UE4SS.
• community-wiki - The community wiki: confirmed features, suggestion guidelines, templates for level, item and entity suggestions, and a guide to running the game on Linux.
• etb-speedrun-bot-v2 (Python) - The speedrunning bot behind the leaderboards and run verification, "The Watcher", originally by @Reokin. Members link their speedrun.com profile and the bot keeps their roles up to date.
