The system includes multiple variants (Horeca/Restaurant POS, Retail POS, Kiosk Ordering System, Donation Kiosk, and related modules). Our solution combines local and cloud functionality, integrates with various peripherals, and requires a modular architecture for long-term scalability.

Your Responsibilities:

• Build and optimize front-end interfaces for restaurant POS, retail POS, kiosk applications, and admin portal.
• Integrate hardware devices such as:
 – Cashmatic 460
 – PAX / [login to view URL] terminals (A35, A920)
 – Receipt printers (Epson ESC/POS)
 – Scales (Bizerba, Elzab, Neptune2, Aclas OS6)
 – Scanners (Magellan, Honeywell, etc.)
• Implement hybrid database logic (local SQLite + cloud API sync).
• Support multi-device usage: Windows desktop, Android kiosk terminals, web versions.
• Improve stability, performance, and offline-first behavior.
• Assist with packaging (Electron build, installers, EXE/APK generation)." (client-provided description)
