Dear Sir/Madam,
I am native Polish speaker with English at C1 level (proved by the exam), with Russian at B1 and learning German at A2/B1. I am a student having classes in English, too. In meanwhile I do translations of technical texts, English-Polish (both ways). I find myself perfect for this job, despite of the fact that I do not know what you might expect from me as a future employee. I would like to meet the challenges and make your project work in the best way!
Yours faithfully,
Marta K.
