I'm Eric. I run Cornerstone Digital from Poole, Dorset, and I build AI-powered platforms solo — design, code, deploy, support, all me.
No account managers. No offshore teams. No "I'll check with the developer." You talk to the person actually building your product, every single time.
I started by building products for myself — Dinara, AgentAI, MyTradeSite. That means when I build for you, I'm not learning on your dime. I'm using the same stack, the same patterns and the same AI infrastructure that already power thousands of users in production today.
