grammar - Do I use a semicolon before 'and' in a complex list?

I am listing things in a sentence which includes commas between the internal parts. Do I finish with an 'and' at the end of it? For example:

I arrange interviews through phone and film; co-ordinate the editorial
team’s travel; and I write blog posts, articles,

and reviews of local London events.

It would be great if I knew the definitive answer, or any tips on how to restructure this.
