Expert Shopify 2.0 Developer Needed for Premium Fine Art Consignment Gallery (Custom UI/UX & Dynamic Framing)

We are commissioning a highly customized, gallery-grade digital storefront for our online art gallery, operating under our parent enterprise, PAT & J.K. Co. (PJK). To protect our business from the tax burdens of an Electronic Commerce Operator (ECO), this platform must be engineered strictly as a curated consignment gallery, not an open marketplace. Single Merchant of Record: The checkout, payment gateways, and invoicing must legally route all transactions exclusively through PAT & J.K. Co.. No Multi-Vendor Dashboards: To prevent ECO classification and mandatory GST registration for our artists, independent creators will not have seller logins or backend access. All catalog data, pricing, and dedicated artist profiles remain 100% under our administrative control. 2. Front-End Discovery, SEO, & Gallery Aesthetics The storefront must reflect a serene, premium gallery wash that balances vibrant artwork with a calm, deliberate layout, completely optimized for technical SEO and high-end visual discovery. Digital Room Mockups & Macro Zoom: Product pages must feature an interactive wall-scale visualizer allowing buyers to accurately proportion the artwork in minimalist or modern interior settings. Additionally, you must implement an ultra-high-resolution dynamic zoom so collectors can inspect canvas weave, heavy impasto, and 3D relief work without page lag. Dedicated Artist Imprints: Gated showcase pages that highlight the artist’s biography, creative statement, and their curated collection of works, all routing seamlessly back to our central checkout. Automated SKU Generation: You must implement a script or system to assign a unique sequential identifier (e.g., PHUL-CV-015) to every one-of-a-kind piece, ensuring the item automatically locks to "Sold Out" once purchased to prevent double-selling. Analytics & SEO: The architecture must be built with clean, SEO-friendly code. We require a private-facing website view counter on the storefront and a comprehensive backend analytics dashboard to track visitor engagement, geographic traffic, and conversion drops. 3. Admin-Controlled Dynamic Framing Configurator Because we source frames locally, the website requires a robust, custom-coded framing upsell widget integrated directly on the product pages. Custom Uploads & Assignment: The backend architecture must allow our admin team to upload new custom frame designs, set their individual pricing, and manually toggle which framing options are available for specific artworks. Variable Frame Types: The widget must allow buyers to toggle between standard raw wood, gallery floater frames etc. Clean SKU Logic: The framing selection must dynamically update the final cart price in real-time without cluttering our Shopify backend with duplicate parent SKUs. 4. Artist Consignment Intake System Instead of a vendor backend, the site will feature a streamlined, gated "Artist Open Call" submission portal for intake. Data Collection: Artists will use this front-end form to securely submit high-resolution photos, exact canvas dimensions, medium details, their PAN/bank details, and their artist bio. Identity and Payment details should be asked to first time artists and for repeat clientele appropriate system shall be set up. Admin Publishing: These submissions must route directly to our private curation queue. Once approved, our admin will manually upload the piece, assign the custom frame options, and publish it to the live store. Plus a custom catalogue feature is required which holds details and metadata of uploaded artwork. This is expected to be a custom feature which allows the admin to manually select entries and metadata and publish it in a pdf format. 5. Architect & Interior Designer Trade Program To capture B2B interior styling sales, the site needs a dedicated, password-protected Trade Program portal that incentivizes architects and decorators. Project Registration ("Lead Lock"): A system where designers register their client projects to lock in their trade commission and prevent payout disputes. 6. Statutory Taxes, Payments, & Global Commerce Automated Invoicing: Seamless integration with a Shopify GST application that generates legal PDF tax receipts stamped with our PAT & J.K. Co. details, dynamically applying HSN 9701 for original hand-painted canvases and HSN 4414 for custom wooden frames. Payment Gateways: Secure API integration for domestic UPI, net banking, and credit cards routing directly into our central current account. International Geolocation & Multi-Currency: Implementation of cookies and IP-based currency switchers that automatically display pricing in USD, EUR, or GBP for foreign collectors without glitching upon checkout. Global Logistics Protocols: Checkout integration with premium international couriers calculating real-time freight. The system must specify that international orders ship strictly as rolled canvases in heavy-duty tubes, accompanied by a physical Certificate of Authenticity.
