However, the Continental Congress elected what could be considered the President and under the Articles of Confederation John Hanson was the first "president" elected

Beyond a similarity of title, the office of President of Congress "bore no relationship" to the later office of President of the United States.

John Hanson was the first president elected under the terms of the Articles of Confederation in November 5, 1781. There were 8 President of the Continental Congress prior to him and 7 after him.

Cyrus Griffin was the last President of the Continental Congress and ended his term in November 15, 1788.

Keep in mind under the Articles of Confederation, the United States had no executive branch.
