Build me a premium, responsive portfolio website with a clean landing page that lets visitors choose between two paths, Full Stack Developer and UI UX Designer.

The main page should have a modern split screen feel with smooth hover interaction, glassy styling, and a polished first impression. When someone picks a side, take them to a separate page that feels tailored to that role. The developer page should highlight projects and include smooth motion and subtle scroll animations. The designer page should feel more visual and creative, with a strong focus on typography, layout, and smooth scrolling.

Keep it fast, mobile friendly, and professional. Use simple HTML, CSS, and JavaScript, and add tasteful animations where they improve the experience. Make the whole thing feel like a high end personal brand site, not a basic template. If you need to check anything modern about animations or browser support, look up current docs online first.
