Project: EOL Diagnostics, OTA Software Updates & SOME/IP (VSS-based Communication Platform)
Description:
Leading the design and development of a scalable automotive middleware platform enabling End-of-Line (EOL) diagnostics and secure OTA software updates for ECUs. The system integrates a service-oriented architecture based on SOME/IP, aligned with Vehicle Signal Specification (VSS), enabling standardized vehicle signal access, control, and event-driven communication across distributed ECU systems.
Key Contributions:
Architected VSS-based distributed client-server system using SOME/IP (vsomeip, CommonAPI) enabling scalable and loosely coupled ECU communication
Designed service interfaces and IDL definitions, including code generation pipelines and integration workflows
o Developed VSS client and server components supporting:
o Signal read/write APIs
o Event subscription and notification mechanisms
o Service discovery and dynamic binding
o Implemented OTA software update workflows, including validation, fault handling, and rollback mechanisms
o Developed UDS-based EOL diagnostic features for production line validation and automated testing
o Worked on serialization, IPC, and network communication layers using vsomeip middleware stack
o Performed system-level debugging using DLT logs, Wireshark, and protocol tracing tools
o Contributed to LLD design, sequence diagrams, and system integration activities
