Retail

Build me an in-house point-of-sale (POS) system, Arabic RTL-first with English support, that runs on the browser, tablets, and checkout devices, and links all branches to a single, real-time inventory. Make the sales screen fast with barcode scanning, automatic totals, discounts, returns, and shift close-out, with an offline-first mode that automatically syncs transactions once the network returns. Apply fine-grained roles and permissions (RBAC: cashier, branch supervisor, general manager) and secure login with hashed passwords and an audit log for every sensitive action. Design the architecture to handle millions of transactions through a database indexed and partitioned by branch, caching for best-selling products, and task queues for inventory sync and heavy reports. Add protection against common attacks, rate limiting, daily backups, and monitoring and logs (observability) per branch. Connect ZATCA e-invoicing and mada/Apple Pay payments through Moyasar or HyperPay from the secrets vault. Deliver the system production-ready with a professional user experience, tests, and short documentation.

Build me a customer-facing online store (website and Expo mobile app), Arabic RTL-first with English support, that shares the same branch and POS inventory in real time so quantities never conflict. Display products with categories, search, filtering, and images, and support a cart, checkout, pickup-in-branch or delivery, and order tracking. Add customer accounts with secure login and roles and permissions, and protect data with encryption, protection against common attacks, and rate limiting. Design the architecture to scale to millions of visitors during sale seasons through a CDN, caching for pages and products, task queues for processing heavy orders and notifications, and a database indexed to handle high load. Connect payments (mada, Apple Pay, Moyasar, or HyperPay), ZATCA e-invoicing, address maps, and WhatsApp/SMS notifications, all through the secrets vault. Account for accessibility, performance, and speed, and add monitoring, analytics, and logs. Deliver it production-ready with tests and short documentation.

Build me an automation engine for retail reordering and pricing, Arabic RTL-first. Have it monitor stock levels per item and branch, automatically calculate the reorder point based on sell-through speed and seasonality, and generate suggested purchase orders for suppliers with a notification to the responsible person via WhatsApp or email. Add automatic pricing rules and promotions (discounts on slow-moving items, bundles, branch-specific pricing) with human approval before activation. Apply roles and permissions (RBAC), secure login, and an audit log for every automated decision. Design the architecture to scale using task queues and scheduling for heavy jobs, an indexed and partitioned database, and caching, so background operations never slow down the checkout even with millions of inventory movements. Add security (encryption, protection against attacks, rate limiting, backups), and monitoring, logs, and alerts when any job fails. Connect WhatsApp and SMS from the secrets vault, and deliver it production-ready with tests and short documentation.

Build me a mobile app (Expo) and a PWA for a loyalty program and customer experience, Arabic RTL-first with English support, linked to the POS and store in real time. Give every customer a points wallet that grows with every purchase (in-branch or online), with membership tiers, coupons, gifts, and a membership card with a barcode/QR for use at checkout. Add notifications and personalized offers based on purchase behavior, sent via WhatsApp, SMS, and push notifications. Apply secure login, roles and permissions (customer, marketer, manager), and protect customer data with encryption, rate limiting, and protection against common attacks. Design the architecture to scale to millions of members through an indexed database, caching for points balances, and task queues for sending mass campaigns without slowdown. Account for accessibility and performance, and add analytics on customer behavior, a campaign management dashboard, and monitoring and logs. Connect WhatsApp, SMS, and AI recommendation tools from the secrets vault, and deliver it production-ready with tests and short documentation.

Design and build me a unified retail platform (backend API + databases) that brings together POS, store, inventory, loyalty, and reporting under a single architecture that scales to millions of users and transactions, Arabic RTL-first with English support. Make the API organized and documented, with a database indexed and horizontally partitioned (sharding/partitioning) by branch and region, and read replicas to separate reporting from sales operations. Apply multi-layer caching (products, inventory, sessions), task queues for every heavy operation (invoicing, notifications, sync, reports), and a CDN for assets. Add centralized roles and permissions (RBAC) and secure login (OAuth/JWT), and full security: encryption in transit and at rest, protection against common attacks, rate limiting, backups and recovery, and a plan for handling seasonal peak load. Add monitoring, tracing, and logs (observability) and alerts, plus load tests. Connect ZATCA, mada, Apple Pay, WhatsApp, and maps from the secrets vault, and deliver it production-ready with short architectural documentation.
