Please help me translate the following words, thank you.

In July 2007, I officially joined McDonald's and became a management team of the operations department as a trainee manager. In September 2007, I was promoted to the second assistant manager of the restaurant. In December 2010, I was promoted to the first assistant manager of the restaurant. During my three years of study at McDonald's, I received professional training from the company. I attended four basic management courses for deputy managers: BSM, ASMC, REC, and EMP. In these courses, I learned more about regional management, store management, and personnel recruitment. In the process of floor management, I learned basic knowledge of restaurant operations and gained experience in maintaining customer satisfaction. In the restaurant, I have assisted the restaurant manager in managing and following up on the personnel system, schedule system, inventory system, safety and security system, planned maintenance system, production system, and food safety system.
