What I built (system design + full-stack development, end to end):
• 5-step plate configurator with live preview and server-side pricing that never trusts the client
• DVLA document verification with an admin review queue
• Order pipeline state machine: received → production → quality check → dispatched → delivered
• Inventory with bill of materials, SKU generation and idempotent stock reservation
• Print-ready plate artwork PDFs, invoices, returns, disputes, coupons and reviews
• Payments (myPOS, PayPal), Shopify / eBay / Etsy marketplace sync, and Royal Mail / DPD / Evri / ShipStation shipping with idempotent webhooks
• Database-driven CMS, blog, SEO tooling and an AI plate assistant
