Hi,
This is a really interesting and diverse project! I have plenty of experience with designing kiosk style POS devices and also with large scale enterprise platforms. I also have a strong experience in embedded development and interfacing software with hardware modules and devices in the IOT industry.
I can cover the software architecture and implementation as well, and I can also contribute to augmenting the product level definition as I have also experience in this field as well.
Looking forward to hearing from you and detailing the project further.
Regards,
Sebastian
