Dual POS System Development for Restaurant & Retail

I'm in need of an experienced POS developer who can create a merged restaurant and retail POS system. Key functionalities for the restaurant POS need to include table management, online ordering, and inventory management capabilities. For the hardware component, I require the system to be compatible with touchscreen monitors, thermal printers, and barcode scanners. Ideally, the freelancer should possess prior experience in developing similar systems and possess deep understanding of integration of these functionalities with respective hardware.
