This translation is quick but quality comes always first.
As I said, I'm native speaker not only in English but also in Czech and Slovak which means I have experienced the culture, slang and also grammar of the countries.
I'm a student which means I spend a lot of time in school (USA school) but my part time job and hobby is translating and I give it all the free time I have (approximately 5+ hours per day).
I'm translating anime and TV shows for almost 3 years for multiple websites. There are also websites I translated to multiple languages, some other documents and also articles. So yes, I have experience and all the people were more than happy with my work!
