Designed real-time embedded software for several generations of “reverse vending machines” (RVMs).

• Designed interactive version to display video advertising and a coupon selection screen, support loyalty card scanning, database integration for customer transactions, etc.

• Designed systems to create, distribute, and vend graphical coupons either selected by the consumer or on a preset schedule.

For Sweden, the RVM connects to web service to retrieve a list of mobile payment providers/coupon logos and XML-formatted receipts.

• Provided tier 3 technical support for global customer base.

Designed Python web app to display RVM status at a location. Users can order supplies, request service/pickup/barcode additions, validate receipts. Created corresponding Android tablet app.
