## App engineering built for real-world use

Building apps and systems people use every day in Iraq has taught us that a successful app isn’t just good screens — it’s architecture that scales, performance on weak networks, secure data and operations that never stop.

### Scalable architecture

We separate UI, business logic and data behind clear APIs, so an app grows from hundreds to hundreds of thousands of users without a rewrite.

- Clean layered architecture
- Documented REST and GraphQL APIs
- Queues and background jobs for heavy work

### Offline-first

On-device storage with smart, conflict-aware sync keeps sales and field work going when the network or power drops.

- Local databases (SQLite)
- Automatic sync on reconnect
- Clear sync-state UI

### Performance on weak networks

Compressed images, progressive loading, caching and small bundles — because most of your users are on average mobile networks.

- First load in a few seconds
- Low data usage
- Performance tested on mid-range devices

### Secure by design

Encrypted transport and sensitive data, fine-grained permissions, secure phone-number login and an audit log of every action.

- OTP and JWT authentication
- Protection against common flaws (OWASP)
- Tested backups

### Local and global integrations

Iraqi payment gateways, SMS and WhatsApp, maps and live tracking, biometric devices and printers, and third-party systems.

- ZainCash, FastPay and Qi Card
- WhatsApp Business API
- Maps and live tracking with Socket.IO

### Quality and 24/7 operations

Automated tests, continuous deployment, error and performance monitoring, and a team that responds 24/7.

- CI/CD with GitHub Actions
- Error tracking with Sentry
- Uptime monitoring with Grafana

## What we build into apps

- Multi-sided apps (customer, driver, merchant, admin)
- Live map tracking
- E-payments and cash on delivery
- Targeted push notifications
- Arabic, English and Kurdish interfaces
- Real-time dashboards and reports
- App Store and Google Play publishing
- Zero-downtime updates
