A New Job

I'm writing my CV for the first time a c.v. in English, language and I'd like know if these phrases are correct:

I have gained organizational skills thanks to the experience either as a secretary., My work included managing e-mails, documents and appointments., I have also worked as an events organiser or as entertainer, where I've contributed towards the management and to organize organisation of events and partys parties for children. I've really enjoyed that experience because I like working with other people, expecially in a multicultural environment., so I can am able to  work well as a member of a team.

Is correct the use of either and or?

I understood your meaning completely, however, this is more natural sounding. I hope I have helped. Your english is good!
