I will proofread you text using word track system, so you can check the changes and compare with your original text.
Besides, I will add comments to help you understand why the changes have been made.
I have experience proofreading university projects in Spanish. I also have publications in academic journals from Spain, Mexico and Argentina. If you need an academic text, be sure I can help you.
I also have experience proofreading texts for websites, blogs, etc.
Let me know where you will publish/use the text, and I will take it into consideration when proofreading and improving it.
