My reasons of studying English.

Hi, my name is Mu-ik Jeon. I was born in Seoul and live in Seoul, Korea.
I'm a software engineer developing the smart phone apps.

Recently I decided to study English. Bbecause I feel need it so much. (I don't think there is anything wrong grammatically, but I would change the second part of the sentence to something like this: "because I feel I really need to learn it.")

First, Iin my company, I work on a project with a foreign company using English. But I can't communicate them well without helping from my project manager. (I think you are trying to say that you sometimes need help from your project manager to communicate, right?)

Second, open source is the community of the programmers. Almost all popular open source projects are communicated (I would use "discussed in English" or "All open source projects use English") with English. I want to wanna participate in the communities. ("Wanna" is informal speach, which is cool, but you probably not want to use it in a more formal setting)

Last, I would have a chance to go (to a )the tech conference in San Francisco, US. OnAt the conference, there are several benefits, such as learning thenew skills, meeting the people who like the tech and so forth. (I would rewrite the sentence to read: "There are several benefits to attending the conference, such as learning new skills, meeting people who are into tech, and so on."

So I have to learn English to enjoy my job and the benefits.

Thanks for reading my note.
Please help my note correct.
