The Gallery: things Rees Calder has built

A walkable 3D gallery. Each piece is a real, working website. Sites that allow embedding are browsable live from inside the room; the rest are shown as captures and open in a new tab.

• Levity — The agency. Turns the dead leads already sitting in a CRM into booked meetings, using AI email and SMS. This one pays for the others. Built with Next.js, Lead gen, Founder.
• EPC Guide — Consumer platform. Every UK rental has to hit EPC C by October 2030. This works out what that costs for one specific property, which grants apply, and the cheapest route there. Built with Next.js, Supabase, Programmatic SEO.
• BookerBot — Voice AI. Answers the phone, works out whether the caller is worth booking, then books them. Qualifies, schedules, confirms. Nobody human in the loop. Built with Voice AI, Webhooks, Calendly.
• EmployerKit — Compliance tools. UK employment law for people who are not lawyers. Plain English, kept current with the Employment Rights Act. Built with Next.js, Content, Compliance.
• PurpleGlo — Pitch as product. A sales pitch built as a working product, for one prospect. Interactive WebGL hero, real numbers, no slide deck anywhere. Built with WebGL, Shaders, Sales.
• CMS Surveyors — Client blueprint. Calls, WhatsApp and email into one brain that files the result back into the system of record. A phone system can summarise a call. It cannot raise the task. Built with Architecture, Comms, Integration.
• Kern — The thing that built this. An always-on AI operator on the Claude Agent SDK. Durable memory, its own runtime, a tool layer, sub-agents. It runs my business and it built this room. Built with Claude Agent SDK, Supabase, Railway.
• The Anthropic Pitch — Application. A pitch built by the thing it describes. Written for a Forward Deployed Engineer role, on the argument that I had already been doing the job for a year. Built with Pitch, Next.js, GSAP.
• reescalder.com — You are standing in it. The site this gallery is a room inside. Fifteen years of marketing and product, now spent building the systems instead of advising on them. Built with Next.js 16, Three.js, Vercel.
