I wrote /I've written a book

Hello,

Can we use the Past simple and the Present Perfect interchangeably here, please?


"You know, I wrote/I've written a book about Human resources"?

Thank you
Will

You can use either but I would follow "I wrote" with some kind of timescale.

I've written a book about Human Resources.
I wrote a book about Human Resources last year.
