full Stack Shopify Developer for Dual Mode 3D VR E-commerce Platform

We are developing an advanced dual-mode e-commerce platform featuring interactive 3D animations and readiness for future VR integration. A core requirement is building a seamless frontend toggle that instantly shifts the site's theme, backend logic, and product catalog between a standard experience and a high-end luxury mode for precious metals. Since this project involves proprietary architecture, we are seeking a dedicated developer for a long-term role with the potential to lead a remote team. Please review these specifications and let us know your proposed budget for this initial build and your estimated timeline for completion.
