I have a keen eye for detail and after years of experience and training I am able to offer both editing and proofreading of texts in Spanish.
Native speakers are usually recommended for this kind of jobs, since we can appreciate small details in the tone and the phrasing of the text and alter it to sound more natural to the final reader.
Editing is the act of modifying whole sentences or paragraphs in a text to make it flow, improving it and making it clearer.
Proofreading is the process of reviewing the edited text focusing on grammar, spelling, typos and punctuation.
Whichever you need, I will adapt to your needs and to the tone you want to give to the text, creating an attractive and coherent final product.
