Lots of ways to do it, but the opening reminds me very much of H.P. Lovecraft, who might well have started something like this:
I am Basil Elton, keeper of the North Point light that my father and grandfather kept before me.
-- "The White Ship", opening sentence
In other words, if you wanted to put your main character's name up front or very early in the text, you might well do it something like that. Here's a coupla samples:
I am Basil Elton [adding as much or as little elaboration about this character as desired]. If I had known yesterday what was to be, what was to come, I would have...
Or you could go all second-positioney, likey thissey:
If I had known yesterday what was to be, what was to come, I would have barracaded [typo] the doors, locked all the windows and retreated from the outside world completely. I didn't know, though. No magic eight ball or tarot cards would have predicted the grim events that lay ahead. Destiny already had my fate in mind and there was no way around it. Even when the old crone came to me, offered the warning, my hand had been dealt. I wish I would have listened. I am Basil Elton, a doomed man, and this is my story.
Of course H.P. also used
this approach, which is the first paragraph from "The Temple."
(Manuscript found on the coast of Yucatan.)
On August 20, 1917, I, Karl Heinrich, Graf von Altberg-Ehrenstein, Lieutenant-Commander in the Imperial German Navy and in charge of the submarine U-29, deposit this bottle and record in the Atlantic Ocean at a point to me unknown but probably about N. Latitude 20 degrees, W. Longitude 35 degrees, where my ship lies disabled on the ocean floor.
Clearly H.P. is getting his main characters' names into these stories from the get-go, and in the former case we're getting the story told by Basil Eaton in traditional narrative form, whereas in the latter we're reading the log entries of a doomed submarine captain.
Those matters aside, advice given by others is pretty much the only real rule, here. Gotta put the name in only where it makes logical sense in the course of the story. If it doesn't have a place of logical and aesthetic fit, it'll jar readers like an unexpected pothole on the otherwise smooth storytelling superhighway.
