I can comprehensively write feedbacks on anything.

What you'll be getting

I can give you:
- A comprehensive feedback
- Suggestions on how to further improve your product or service

Note: My work will be in written as if it was a newsletter unless you want to give me a specific format.

As a "Jack-of-all-trades" kind of person, I'm pretty flexible on the wide range of things or topics I could do feedback on.

Feedback, for me, is a great way to know what a person could further improve within himself/herself. From a business perspective, it could potentially be helpful by learning from those feedbacks to further improve a product or service.
