qaira is a production-grade walk-in management system — built from a real problem, deployed on real infrastructure, serving real guests.
My friend and hairdresser works without appointments. For years, the system was simple: you walk in, he sees you, he remembers the order. Then you wait — somewhere, somehow — and hope to be back in time.
I built wait2go, a first version that digitised exactly this: walk in, register once, leave, get an SMS when you're up. No app. No account. Just a phone number.
qaira is the next iteration — rebuilt from scratch, production-ready, multi-tenant, with a prediction engine, a full notification system, and the kind of infrastructure quality I'd expect from professional software.
A running system. With a pinch of magic, and a lot of coffee.
Built around the guest experience — the moments that matter, the details that make the difference.
A full production stack — reverse proxy, application server, task queue, cache, database, and a custom SMS gateway — each component chosen deliberately and configured properly.
Every service configured for real-world operation — monitoring, backups, automated deployments, and a custom SMS stack that runs on its own dedicated hardware.
Security and architectural rigour were first-class concerns from day one — not retrofitted. The system was designed with clear trust boundaries, then formally audited across authentication, data isolation, PII handling, and communication security.
