Hello. My name is Aileen, I'm a Venezuelan journalist/editor and independent translator. I can translate the content of you app to Spanish, no grammar or spelling mistakes. Venezuelan Spanish is neutral.
You can check my profile and see my reviews, I have experience translating apps and websites content. I can work with Word, Excel, Notepad++, Poedit and .txt files in case you don't have your own translation platform.
I usually work with a per word rate. If you contact me and give me more details about the project (total number of words to translate, type of file, desired deadline, etc.) I could come up with a better offer.
Have a nice day!
