PWA Developer for Inventory System and Cross-Listing App

Job Title: Mobile-First PWA Developer for Reseller Inventory & Cross-Listing MVP Description: We require an elite full-stack engineer to craft a mobile-optimized Progressive Web App (PWA) serving as a centralised inventory terminal and semi-automated listing companion for clothing resellers (Target: eBay & Vinted UK, Depop). CRITICAL ARCHITECTURAL CONSTRAINT: You must NOT implement a backend server-to-server automated engine (e.g., node scrapers, background server Puppeteer, AWS headless clusters). Target nodes are Confidential — For Internal Use Only Page 3 of 4 Listly — MVP Development & Launch Roadmap protected via enterprise cloud defenses. All automation, fields populations, and listing cleanups must run client-side using JavaScript DOM injection parameters inside the user's localized mobile device browser space to leverage active localized user session states and cookies. Key Deliverables: 1. Responsive PWA architecture (Next.js/React preferred; storage via Supabase or Firebase DB ecosystem). 2. Monolithic Inventory Input System mapped to targeted platform attribute schemas. 3. Client-side browser scripting component to inject item datasets straight to active Vinted creation pathways. Final submission is manual. 4. eBay Developer REST API structure integration to natively monitor active transactions. 5. Prompt assisted delisting pipelines triggered immediately upon eBay transactions notifications via safe client views instances. 6. Operational Stripe recurring checkout paywalls integration. Budget: TBC (Stated Milestone Contract). Application Requirement: State explicitly how you plan to navigate Vinted's Cloudflare anti-bot rules without causing users' profiles to get flagged.
