Full-Stack Developer for Custom iPad Production Tracking PWA (Tailwind UI + Supabase)

We are looking for an experienced Full-Stack Developer (React / Next.js) to build a fast, ultra-clean Progressive Web App (PWA) optimized for a 13" iPad screen. Important Note: All UI/UX designs and layout components will be provided by us via a licensed Tailwind UI package. You do NOT need to design the UI. Your main job is to structure the database, integrate the components, handle dynamic logic, and connect barcode/QR scanning. Core Requirements: Data & Progressive IDs (Supabase): Auto-generate progressive Client IDs (e.g., LIT-CL-001) and Order IDs (e.g., LIT-C-085). Support multi-tenancy & custom B2B client logos on order sheets. Dynamic Pricing & Visual Options: Visual grid for shirt customisation options with photo previews (Fabrics/Textiles, mother-of-pearl buttons, collar styles). Real-time total price calculation based on selected options and B2B custom price lists. QR Code Generation & Barcode Tracking: Auto-generate a unique QR code for each printed production sheet. Dedicated station views (Cutting, Assembly, Ready, Store). Scanning a QR code auto-updates order status + timestamp without requiring extra taps. Tech Stack Required: React / Next.js, Tailwind CSS, Supabase (SQL database). Project Structure & Milestones: Total Budget: $500 (Fixed Price) paid via 3 Milestones: Milestone 1 ($150): Database setup, Tailwind UI integration, progressive ID logic & multi-tenant logos. Milestone 2 ($200): Visual options catalogue, real-time price calculator, dynamic QR code generation & scanner station interface. Milestone 3 ($150): iPad PWA testing, bug fixing, and final production release. Please apply with examples of React/Tailwind/Supabase projects you have built. Native/fluent English communication via text/Loom video is mandatory.
