Can I vibe code ProShip?

Build a high-throughput shipping execution API proxy in Node.js and PostgreSQL designed for ecommerce warehouse integration. 1. DATA MODEL: Schema for Shipments (id, order_id, status, weight_oz, length, width, height, origin_address, dest_address), CarrierRates (carrier_id, service_name, rate_cents, transit_days), and Labels (shipment_id, tracking_number, zpl_data, label_url). 2. RATE SHOPPING ENGINE: Implement a POST endpoint `/api/rates` that accepts shipment details, concurrently queries mock APIs (or integrated APIs like EasyPost/ShipEngine) for FedEx, UPS, and USPS, applies business rules (e.g., select cheapest service under 3 days transit time), and returns sorted results within 300ms. 3. LABEL GENERATION & PRINT QUEUE: Implement a POST endpoint `/api/shipments/buy` that purchases the chosen rate, fetches the raw ZPL string, saves it to PostgreSQL, and pushes a print job payload to a local Redis-backed queue. Implement a worker process that reads from Redis and streams raw ZPL bytes over TCP socket directly to a local IP address thermal printer (port 9100). 4. ERROR HANDLING & FALLBACKS: Handle API timeouts, carrier address validation errors, and network print failures by flagging shipments as 'PRINT_ERROR' in PostgreSQL and notifying a Webhook endpoint. 5. OUT OF SCOPE: Do not build dangerous goods/HazMat documentation generation, physical scale RS-232 serial communication, or complex customs clearance EDI generation.
