I have more than 4 years of experience in the field of Automotive Engineering. I have more than 3 year of experience in ISO26262 functional safety process as a System Safety Engineer. I am a certified Automotive Functional Safety Professional from SGS-TUV. As a safety engineer, I worked on various safety work products such as creation and documentation of functional safety concept (FSC) and technical safety concept (TSC), performing quantitative and qualitative analysis using FMEDA and FTA, drafting of safety requirements at different architectural level and provide traceability in a requirements allocation system (DOORs). I have hands-on experience in tools such as CANalyzer, CANoe, CANape and in performing specific safety tests, such as fault-injection testing at bench and in vehicle. I am also a SAE certified Controls and Calibrations engineer from LHPU with hands-on gasoline engine control systems and calibration, including model-based designs by using MATLAB and Simulink. In addition to this I have worked with microcontrollers, sensors, integrated circuit designing and in various

communication protocol such as CAN, SPI, I2C and UART. Education:
