Could anyone correct this?

This is an introduction about me I'll write in my profile. Could anyone can help me correct this? Especially I'm really especially confused about articles like 'a' and 'the'.

How are you? I’m Jenna from Seoul.

I graduated from university here. I’m currently working for an international company as an administrator.

When I’m working, I often came across situations where I am required to speak in English. But whenever I speak in English, I’m almost I start freezing and getting too nervous. because I don't get many opportunities to speak in English. so My writing is okay, but I’m not confident in speaking in English. This is why I am looking to speak with many people who are interested in learning Korean language. I guess most people who want to learn English are also very interested in Korean culture and celebrities. You can ask me whatever you’d like to know about Korea. Let’s learn together! :)
