Client wanted to move the current website to AEM while keeping an identical look and feel. while reusing as much as the frontend code (HTML/CSS/JS) as possible.
We used our proprietary product GX2CMS, which allowed our developers to develop frontend code that was AEM ready in record time. A website with five template variations (homepage, products page, etc...) will take approximately 80 hours to complete in GX2CMS + 40 hours to integrate and function in AEM which the client can go live with.
There is no vendor lock-in in using GX2CMS. The code is independent and not a line of it gets deployed onto AEM.
