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
• 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, ~5,400 lines of JS, ~5,650 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; makes the Pi will reboot 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

• 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.
