Designer tomjohndesign launched Tomjohnville, a game-like portfolio built almost entirely with Claude Opus, sharing the full stack: Three.js + Next.js on Vercel, multiplayer characters via Cloudflare Workers + Durable Objects, Neon + Drizzle ORM, Resend, and Figma. Notably, performance tuning consumed 30-40% of all tokens spent on the build — and it's still not perfect.
