Hello,
I started my work as a translator of Korean and English on freelancer.com in March.
However, I have already finished a translation of a 200-page biography book of Lee Kun-hee,
Samsung's CEO last month.
I got a good review for my fast and accurate work.
I am a native Korean who learned English from my foreign language high school and lived abroad for about 8 years.
Especially, if you are looking for a person for your language-learning app, I would be a proper person because I worked for 3 years as Korean teacher for Korean-French children in Strasbourg. Me, myself, also, I love learning foreign languages. (you can see my language ability on my profile page.) So, I can understand how this kind of translation should be done for learners. Working with Excel is not difficult at all for me because I got a certificate for it when I was a university student and I use it very often in my daily life.
I always work very hard and intensively, so you don't have to worry about the deadline if it should really be done until the 24th of April. Finishing it earlier than this date would be difficult because of the Easter holiday.
My skype ID is jjinnykim.
Looking forward to working with you, just feel free to contact me, please.
