Always look for more new challenges and opportunities to learn more and fill up my starve about learning and achieving more challenges, that pushed me to work in training Department and technical support Department, then to 'Management' science to Learn how to take the best advantage of the workshop in accordance with high standards. which acquired me a wide experience in French brands like Renault, Korean brands like KIA and Hyundai, Chinese brands like DFSK, and so many other different brands and models on which I worked on to go through more challenges and gain more experience.and one of the challenges which i am proud to go through it, is at the beginning when worked on the Chinese brand there was no support from the mother company with information to help us in diagnosing any problems like wiring diagram and reference values for ( sensors, actuator and solenoid valve .….etc )which drove me to draw wiring diagram for some system on the vehicle, keep records and values as a reference taken from new vehicle to facilitate solving technical problems and diagnosis. Also, modified cooling system design to solve engine overheat without existence of any defect in the cooling system parts, and this experiment gave a positive results and worked well.
