I am looking for a serious web backend developer who has skills in high performance server apps. My project is a mobile based QR code scanner and backend server app to allow the playing of selected videos and /or events or apps on the mobile device based on the QR code scanned.
I am looking for someone to provide me both the mobile side ( ideally use existing QR code scanners ) and server side running in an AWS EC2 instance. Its a relatively simple app, but it needs to be small and fast. Have full specs for selected party.
