Who Builds This?

I'm Jan, a full-stack developer from Prague.

I built SkyPhaze – an AI assistant now used by 535 paying customers – in just 3 weeks. I didn't use a team. I didn't have a big budget. I just built fast and smart.

I connect everything: AI, payments, automation, beautiful UI. You bring the idea. I make it real.

Now I help founders and entrepreneurs build their own profitable AI products.
