Senior Native Android Developer (Kotlin) We have a mobile application running on an Android 7.1 POS device. The task of our application; It is to communicate with Vending Machine, to which it is connected, over MDB protocol, to read debit and other mifare cards contactless, contactless and magnetic and to receive payments through its APIs. We already have an existing application and it is integrated with VMC, it can make sales transactions and receive payments. If what we want to do - direct bank integration (AIDL app integration) - Reading Mifare cards contactless and collection from APIs according to UID value - Integrating new UX designs into the project - Integration with Kiosk via MQTT - Integration with USB - Log storage structure within the application - Stable and performance code development - Scalable code development We have a separate application for bank integration and we have converted this application to AIDL format for you to call. We will share the source code of the demo application for AIDL integration. You can see how to do it from there and proceed directly as copy/paste. Our aim in MQTT integration is to send commands to our device and receive payment via MQTT. In this context, endpoints that trigger several functions such as payment, cancellation, refund and end of day will be created. Also, MQTT broker will be in our Android app. For each of the above requirements, we have arguments such as flow diagrams and information on how to do it, documentation, SDK. I will be supportive throughout the whole process as I myself act as the CTO. But we want to produce a fast and performance project with a Senior candidate. Our project is currently working and improvements will be made on it. All the enhancements are actually simple and very easy for Senior Developers. Time and budget have been determined by taking into account the workload. It will start with one nomination by Friday. Conditions; - NDA and IP contract is mandatory. - It will start this Friday and will be delivered within 10 days. - All payment will be released after each development is completed and tested. Otherwise, no payment will be made. - There is no difference between weekdays and weekends and we want service for 10 days. - With the 10-day development plan, test times will be determined and I will participate in the tests with the device and we will test it online. - Guaranteed to work for 30 days after all development is complete is a must. - Requirements may vary by 10% during development. The developer will not object to this. I want you to write "66" at the beginning of your offer. Good luck.
