Hello We have worked with Raspberry based POS developement using C++ and QT, before. The OCPP protocol is new to us, but we can do it. The server will be running a X64 or X86 architecture, we assume and the client will be using the ARM architecture, i assume. Probably, more information will be required to understand this project properly. My expected completion period will be around 40 to 60 man days, where the alpha version can be released in 40 days, followed by a beta 1 and beta 2 in 10 days. Please inform, how you think about our proposal. Our bid stands on 17-20 USD per hour, though mentioned to be 45 in the bid. To summarize: • Linux - Yes, Ubuntu and ArchLinux • ARM based embedded Linux systems - Yes, ArchLinux • C and/or C++ - Yes, 13+ years • GTK Framework - Not done • XML - Yes • Full stack developer that understand network and application layers - We are good • Familiar with Linux based software and embedded ARM systems - We are okay • Integrate USB RFID code into custom application running on a Linux system - Its a programming thing, with the RFID SDK, IMU. • Integrate video playback into custom GTK based UI - Not done before • Understand and Implement Open Charge Point Protocol (OCPP) protocol - Not done, but if its a TCPIP based communication, we are okay with it. • Design and build server and client application utilizing the Open Charge Point Protocol (OCPP) - Okay Good day.
