I built many cross portals and Kajabi one of the main tools now I used, all in one setup from branding design system to custom UI builder to the custom code that give me more capabilities to integrate + solid backend and safe payment. With my engineering expertise feel free to suggest and propose your own concept scope because I'm using all what Kajabi provide + More advanced like MCP and Custom code implementations. Open up this particular service for who want all in one Kajabi website or platform, I will be happy to proceed.
