Using "and" twice in a list?

Question

About using *and*, I've learned it is usually used in lists, between the last two items. For example: >I like movies, traveling *and* going out with friends. Please tell me if the use of *and* twice in this next example is correct. The first *and* is used between the last two items of the list, and the second is used to combine two things in the second part. >I am a software developer who has permanent residence, Bachelor degree **and** 4 years experience in .net for developing new software **and** doing enhancements in existing once.

Answer 1

Using "and" twice in a sentence is colloquially acceptable. It is possible to repeat "and" more than once in a sentence, as long as you think its the best way to convey your meaning. However, although there are no grammatical rules that limits the use of "and", it is recommended to find a way to complete a sentence without having to employ "and" often. For your sentence for example, it could be devised like the following: "I am a software developer with permanent residence and a Bachelor's degree in engineering. I have had 4 years of experience in .net for developing new software as well as making enhancements."

Answer 2

Change the first "and" to "with" to create a more pleasing sentence.
