Write this section in third-person, meaning you should not use the words ‘I’ or ‘We’ or ‘Me’. Instead, talk about the author objectively using 'he' or 'she' even if you are the author! It’s time to show off your achievements and prove why you are the right person to be writing this topic.
But just after you’ve talked yourself up, make sure you end on a friendly note. You don’t want to sound intimidating, you want to sound knowledgeable and friendly.
