Crowd & Ticketing Management

Build me an internal operations-room system for crowd safety management at major events, English-first with Arabic support. The system shows a real-time dashboard of entries and exits at each gate and the fill level of every zone in colour (green/orange/red), with automatic alerts before the safe capacity is exceeded and a tool to activate evacuation plans and direct the field teams. Make roles and permissions (RBAC) fine-grained: operations director, safety supervisor, gate officer, and a read-only observer, with secure login, two-step verification and an audit log for every sensitive action. Design the architecture to handle a real-time flow of counter readings from dozens of gates via task queues for event processing, caching for the live state, and a database indexed on gate, zone and time with historical data partitioned when needed. Apply world-class standards: data encryption, rate limiting, protection against common attacks, automatic backups, and monitoring and logs (observability) for every alert. Connect emergency alerts to WhatsApp and SMS for the teams, add accessibility for large screens, and make the system production-ready with tests and short documentation.

Build me a public-facing ticket shop for a huge event, English-first with Arabic support, designed to hold up at the peak when booking opens and tens of thousands arrive in the same moment. It shows ticket types, prices and an interactive seat map, holds the seat temporarily during payment, then issues a ticket with a unique, digitally signed QR code per person. Add a virtual waiting room that organises entry at peak and stops the link from stumbling, plus bot-purchase protection and a per-user request limit. Connect payment with mada and Apple Pay through Moyasar or HyperPay with API keys in the secret store, and issue a ZATCA-compliant electronic invoice for every transaction. Design the architecture to scale to millions of visitors: a database indexed on event and seat with caching for the product pages, queues to process payment and issue tickets asynchronously, and a content delivery network (CDN) for images and static assets. Apply world-class security: encryption, prevention of the same seat being sold twice via concurrency locks, backups, and monitoring with sales analytics. Make it production-ready with a smooth mobile user experience, accessibility, tests and short documentation.

Build me a full automation engine for the attendee journey at events, English-first, sending WhatsApp and SMS messages automatically based on defined events and timings: booking confirmation and the QR ticket right after purchase, a reminder a day and an hour before the event with the gate number and entry time, an instant alert when the gate changes or congestion occurs, and a thank-you message and survey after the event. Add a visual builder for automation flows (triggers, conditions and steps) and customisable message templates, with roles and permissions for who designs the flows and who approves them. Connect WhatsApp and SMS with API keys in the secret store, and design sending to scale to millions of messages through task queues with send-rate throttling and respect for the provider's limits, automatic retries on failure, and caching of each recipient's state. Apply world-class standards: encryption of contact data, rate limiting, protection against abuse, backups, and monitoring and analytics of delivery, open and response rates. Make it production-ready with tests, a log for every message, and short documentation.

Build me a mobile app (Expo) for the event's audience, English-first with Arabic support, that is the attendee's companion from purchase to exit. It contains a ticket wallet showing a dynamic QR code that works offline even on a weak network, and a live venue map showing gates, seating zones, restrooms and the nearest emergency exits, with zones coloured by real-time crowding taken from the entry counters so visitors know where to go and avoid congestion. Add push notifications reminding them of the entry time, gate changes and safety alerts, and secure login tied to the buyer's account with permissions that prevent fraudulent ticket sharing. Design the backend to serve millions of attendees: a fast indexed API, caching for the map data and the live state, queues to broadcast crowding updates, and a content delivery network (CDN) for assets and maps. Apply world-class standards: encryption, rate limiting, protection against attacks, backups, accessibility for older people and people with disabilities, and monitoring with usage analytics. Make it production-ready and Expo Go compatible, with tests and short documentation.

Design and build me a ticketing and crowd management platform that scales to millions of concurrent users across several events at once, English-first with Arabic support, with a clear focus on the architecture. Make the front layer static pages distributed over a content delivery network (CDN), and the backend stateless API services scaling horizontally behind a load balancer, with a virtual waiting room absorbing the peak waves. Design the database carefully indexed and sharded/partitioned by event and time zone, with read replicas for heavy queries, and a caching layer for inventory, prices and the live capacity state. Process payment, ticket issuing and notifications asynchronously through task queues with concurrency locks preventing the same seat being sold twice. Connect mada, Apple Pay, ZATCA and WhatsApp with keys in the secret store. Apply strict world-class standards: full encryption, rate limiting, protection against DDoS and common attacks, backups and disaster recovery, and comprehensive monitoring, tracing and alerts (observability) with logs. Make it production-ready with load tests, short architectural documentation, and the ability to deploy and move the code to GitHub.
