Customer: Chrysler Project: PHEV (plug-in hybrid electric vehicle) controllerAs a software developer in a 4 person team developed a set of system level daemons in embedded linux environment (arm7). The main purpose of daemons was collecting various diagnostic messages from car internals (through CAN bus), gps logging and reporting logs to storage server through gprs channel. 2 of 2 design iterations were done in time and with quality above expectation. I was a single responsible engineer to design and to implement 1/3 of a system (developed 3 of 9 daemons). I suggested, designed and developed a unit test environment (perl) for automated testing of daemons. Largely due to this test framework, the development process was accelerated and the project was rated by management as one of the most successful projects.
