I've been a freelance writer in the health, science and finances spaces for years. With someone who has a Master of Science degree, it's been helpful for a lot of clients wanting to create more digestible content for the general population.
I have assisted with product testing prior to reviews needing to be curated in addition to writing the articles. My book, The Art of Being a PITA, was also published in 2019, so I have experience with the book writing and editing process.
