Hi! My name is Beh, and I love to develop applications. My passion is helping people who are interested in developing applications.
I've helped many enthusiastic students to turn their ideas into reality! Also most of them are now working for companies as a developer. My favorite hobby is "making hard concepts understandable". I try to make learning as fun and as easy as possible for my students.
I've been teaching for many years and during these years I've come to a general conclusion that students can also be my guide. Through my students and their questions, I can find out how they think about developing. So I'll be there for you every step of the way.
