Client: Tata Motors | Project: Connected Vehicle Mobile Platform

A feature-rich connected vehicle application that brings together the full ownership journey for Tata Motors customers — from exploring and booking test drives, to managing service appointments, tracking real-time vehicle health, monitoring device and telematics status, and controlling the vehicle remotely. The platform also keeps customers informed through timely notifications on vehicle activity and service updates.

Key Contributions:

• Developed and integrated RESTful middleware APIs using Spring Boot & Spring MVC, delivering clean and well-structured responses tailored to front-end requirements for the connected vehicle platform.
• Consumed Kafka events for real-time vehicle alerts and status updates, ensuring reliable message processing within the microservices layer.
• Implemented Redis caching for authentication tokens and frequently accessed data, reducing redundant database calls and improving API response times.
• Implemented circuit breaker and fallback mechanisms using Resilience4j to handle downstream service failures gracefully and maintain platform stability.
• Collaborated closely with front-end developers to understand business requirements and shape API responses accordingly, reducing back-and-forth during integration.
• Documented all APIs in Swagger, providing front-end and QA teams with a clear and up-to-date reference for integration and testing.
• Wrote and executed test cases, performed API testing using Postman, and supported the QA team during functional testing cycles.
• Monitored API performance through dashboards and alerts, proactively identifying potential issues and coordinating with downstream API owners to prevent downtime.
• Reduced code smells and improved overall code quality by regularly analysing SonarQube reports and addressing flagged issues.
• Handled production issues and participated in root cause analysis, ensuring timely resolution with minimal impact to end users.
• Assisted with deployments and used Kubernetes commands for log tailing and basic troubleshooting, coordinating with the DevOps team for production releases.
• Mentored two junior associates, helping them understand the system architecture, codebase structure, and development practices followed within the project.
