My responsibilities spanned two streams. In the system debug and ADAS validation stream I performed root cause analysis of defects reported during system integration testing — analysing test case correctness, system architecture behaviour, CAN and SOME/IP traffic via CANoe traces, BLF logs, pcap captures, and inspecting AUTOSAR ECU C source code using Lauterbach TRACE32 and Android VM components. I debugged ADAS test failures for ACC, DW and OSE features across a multi-domain environment spanning CANoe signal injection, CarMaker scenarios and the Android CAROS platform. I resolved a critical cross-domain data integrity defect where 50+ SOME/IP signals received unexpected values at the CAROS VM boundary, traced to a CAN-to-SOME/IP conversion defect in the AUTOSAR communication stack.
In the TCU validation stream I developed Python REST API test automation libraries covering interaction with an eCall web server over HTTP and a Windows-based diagnostic tool, implemented UDS diagnostic test automation using udsoncan over DoIP covering extended sessions, security access, routine control and DID validation, and delivered approximately 500 automated test cases for eCall and Cybersecurity features with HTML reporting via Jenkins CI/CD.

12/2016 – 12/2023

Embedded software engineer responsible for the full development and certification lifecycle of the GWX 8000 airborne weather radar software, certified to DO-178B DAL A.
My responsibilities spanned embedded C development on a proprietary RTOS — including signal processing algorithms (clutter suppression, SNR estimation, multi-scan processing), FPGA hardware interfacing for Coherent Processing Interval data retrieval, and TCP/IP and UDP communication stack extensions. I authored system and low-level software requirements, performed source code reviews, and executed tests at unit, integration and system level as part of the DO-178B certification activities.
Beyond core development I built Windows C++ simulation tooling in Visual Studio for radar algorithm development and regression testing, extended an in-house C++ MFC tool, and designed Python-based stress and endurance test suites integrated into Jenkins CI/CD. I also configured and operated the avionics integration lab — connecting the weather radar to a live X-Plane environment driving real PFD and MFD hardware via HSDB and ARINC 429 — performing cross-integration testing of the full avionics suite.

Embedded software engineer responsible for C and C++ application software development on two product lines — a Linux-based flow computer (FloBoss S600+) and a new QNX RTOS-based RTU platform (FB3000) developed from the ground up.
On the flow computer I developed and maintained firmware for fiscal measurement and custody transfer applications, implemented serial communication features, and diagnosed and resolved field-reported defects including a critical Modbus TCP/RTU protocol edge case causing intermittent SCADA connectivity loss across multiple deployed field units.
