Professional Experience

Android Developer, Contus, Chennai, Tamil Nadu, India / AUG 2019 – TILL DATE Title : JCB,

Role : Developing,Bug Fixing,Tes2ng (Development Tes2ng or Unit Tes2ng). Technologies : Android, BLE,Realm,XML,

Team Size : 3

OverView : Device based Applica2on interac2ng with device via bluetooth and data being collected from device by sending Frames based on Protocol Document. DescripLon : As I said Applica2on is developed purely for engineers who all work and Interact with devices in JCB. JCB has major modules like Diagnos2c, HealthCheck, Flashing, Service’s all major modules may differ from each Model in JCB and we developed modules for Both J1939 and UDS protocol. It's a standard protocol followed in the AutoMobile industry. We will have ECU’s (Electronic Control Unit. It’s an Embedded system Controls the Electrical system in Vehicle) which may differ for Each model will be in JCB and to interact with respec2ve ECU we will have a BLE Dongle which will act as a bridge between Ecu and Mobile Applica2on. Frames will be first sent to dongle then it goes to ECU

(APP to DONGLE) Connec2on once our frame has been understood by ECU it will give us a posi2ve acknowledgement (ACK) this process is common for all Requests we follow.We will receive a raw data from ECU and we will extract a respec2ve piece of data on basis of Protocol we follow. Diagnos2c and HealthCheck are similar Ac2vity which will have a slight difference diagnos2c reads all the sensors and Modules in JCB by giving Request and it is a fastest and efficient way of Tes2ng and Troubleshoo2ng the device based on the frame we request.Similarly health check also quickest way to confirm that machine a maintained in good condi2on. Flash is used to replace an old bin (File Format) file with new file in Dongle & Ecu and opera2on has been carried out by sending Frames one by one to Dongle . ResponsibiliLes :

1. Understanding & Developing on the basis of client requirement along with the team. 2. Bug fixing based on severity in Applica2on.

3. AFending the team mee2ng on a daily basis.

4. Following a rou2ne commit in GIT and Logging in JIRA. 5. Maintaining Code standards followed in Projects. 6. Upda2ng a status of work to Team Lead and Manager on a rou2ne basis.
