Project : Stellantis-DOCG (Device Management OTA Console Global)

Role : Back End Developer

• Developing a unified Device Management and OTA Platform that meets the XFCA and XPSA needs using abstraction layer (ABC System) for interaction with other ICT systems and referential to deliver the following: VHL Registration, Software registration, campaign creation and start campaign

Tech Stack - Java, Springboot, Microservices, PostgreSQL, Dockers, Kafka, Redis, Dockers AWS

Roles & Responsibilities

• Contributed to the Stellantis DOCG project by developing the backend for the Device Management OTAConsole Global
• Utilized Java with Spring Boot, Spring MVC, and Spring Data to design and implement scalable and efficient server-side solutions
• Focused on creating robust and reliable backend services to ensure optimal data processing and system performance, supporting the overall functionality of the project
• Write unit tests, integration tests, and end-to-end tests to ensure robustness and reliability of applications
• Create RESTful APIs using Spring Boot to expose the processed data (e.g., battery status, mileage, etc.) to the frontend
• Implement security (authentication/authorization) for the APIs
• Work closely with the frontend team to ensure seamless data flow from backend APIs to the UI

Vehicle Data Processing (VDP)

Role : Backend Developer

• The project was about processing binary data coming from electric vehicles (eg:battery,status,kilometers,etc), the data used to come from the IOT devices of car through Kafka Topic
• We used to process it in our project and convert it to JSON and pass this data to the Frontend were the user can see the data of his/her car.

Tech Stack: Kafka, Java, Junit, Mockito, PowerMock, SpringBoot

Roles & Responsibilities

• Design the relational schema to ensure the structure supports efficient storage and retrieval of vehicle data
• Create RESTful APIs using Spring Boot to expose the processed data (e.g., battery status, mileage, etc.) to the frontend
• Implement business logic to handle data transformation (e.g., extracting relevant fields such as battery status, mileage, etc.)
• Set up Kafka consumers to receive and process binary data from IoT devices embedded in electric vehicles
• Write unit tests for service methods using Mockito to mock dependencies (such as Kafka consumers and repositories) and isolate business logic
• Ensure deadlines are met and the system is delivered on time and within scope
