Revise the above for parallel structure.

"I have mastered the professional skills of export maritime transportation well." The "well" is redundant. You cannot master something badly. If you have mastered it, you have become very good at it by definition.

Your third paragraph consists of a series of vague generalities. What specifically do you hope to accomplish, and how exactly do you expect working for the company to which you are applying to help you accomplish them?

You may use" container and customer analysis, loading rate statistics, and the contact and coordination with..." for parallel structure.

After three year's working experience as a sales assistant, I have mastered the professional skills of export maritime transportation well. I am able to manage normal conditions and emergencies, satisfying the demands of different customers with my strong communications abilities. Moreover, a good command of English enables me to successfully cope with both customers domestic and overseas customers.

^I just want other people's opinion on this. If it is one of the 'largest shipping companies in the world', naturally the company should have a reputed name. If this is the case, is there really any need to say that it is 'one of the largest shipping companies' since the name, if it is that reputed, should be able to speak for itself?
