I build software that lives close to the metal and ships to the edge.
Sean Behan · Ontario, Canada · 12 years building software
12 years of web applications, from database to frontend. I daily-drive NixOS, write Rust and TypeScript, and build everything in the open — a Wayland compositor, bots on Cloudflare Workers, and a pastebin on R2.

Codebam Stream
Browser-first multistreaming in early access: OBS pushes one signal in over WHIP, your own watch page is the program output, and the same signal leaves again as RTMPS to YouTube, Twitch, X, Kick and Telegram. Cloudflare Workers, Durable Objects, D1 and LiveKit underneath, prepaid hours on top.

Viewport
A Wayland compositor in Rust on Smithay whose entire shell — wallpaper, dock, window frames and titlebars — is a web page, composited zero-copy alongside native clients. Five interchangeable engine backends render that same page: WPE, WebKitGTK, Chromium, CEF and Servo.

Telegram Bot for Cloudflare Workers
A lightweight, type-safe Telegram bot framework for Cloudflare Workers: handlers chain off the incoming Request, middleware runs before them, and one URL registers the webhook. 325 stars, 214 forks and 120 releases on npm.

Tux Robot
The bot that grew out of the framework, rebuilt on grammY: one Cloudflare Worker for the conversation, Cloudflare AI for the answers, Tavily for web search and document retrieval, and a Svelte 5 web app in front of it all. Live at t.me/TuxRobot.

Pastebin R2
A pastebin on Cloudflare Workers in TypeScript with Hono, storing objects in R2 behind a small REST API — create, update, list, info, delete — with syntax-highlighted and plain-text views, and pastes that expire on their own.
