The word "than" is used comparatively (to make comparisons) eg. I'm taller than you.
The word "then" is used to describe a position in time eg. I went to the park and then I went to the store.
Your lack of understanding of very basic grammar/spelling really work against the idea that you're this total badass lol. Or, even somebody who understands how things work.
Bonus round: Pro tip, if you have mistakes like these on your resume, your future (not any more) employer will look at other candidates before you. Proper English is important!
