My very first writing

Hi guys! I am hyunwook from South Korea currently living and working in Frankfurt, Germany! (...from South Korea and I am currently...)  I am from Seoul where nearly 20% of Koreans are living at the moment..(I am from Seoul where nearly 20% of the population of South Korea lives.)  yes it is such a huge city compared to the cities in Germany. (Do I need to input "the" before cities or is it fine without the?) (No, you don't need "the". It is a huge city compared to those in Germany)
I am still (don't need "still") a student studying international trade as a major in Korea but I studied in Istanbul back in 2014 as an exchange student. I really loved to be in Turkey. (I really loved living in Turkey.) People had been (were) so friendly to me and especially I'd loved turkish foods! (I especially loved Turkish food!) (which is) one of my favorite foods in the world! (you could say "one of my favorite cuisines in the world!"
My company is a trading company (I work for a trading company) which is importing some goods(which imports goods) from South Korea and exporting them(exports them) to many different European countries including Russia! (don't really need exclamation point here) I do not have a chance to be in charge of foreign sales as I am just an intern but I would like to be one day :) (or some day) (As an intern, I'm not in charge of foreign sales but I hope to be in the future.)
My favorite activity is travelling. No matter how many times you ask me about this (ask me this question)my answer will never change. I have traveled to quite a lot of countries and cities since back in 2012.(since 2012) For example, the UK, France, Beligium, The Netherlands and the list goes on... I really do love travelling and it really has helped me improving myself by(helped me improve myself) in many ways. I have met so many nice people who have inspired me. My life has totally changed since then.

I know my writing is a bit mess.. it is because I am writing this while I am working haha..
If some of you can correct my writing, I would be very glad and pleased!
Thanks a lot in advance!
