Hi, I'm multiplexer and I'm a full-stackoverflow web developer.
English is not my first language, so please excuse any mistakes.
I'm also a teacher, author and freelance consultant, but really, everything come down to "cơm áo gạo tiền"
I've been programming for a long time. More than 15 years. I learnt some HTML, a little CSS, create a forum with php open source like phpbb, and then it snowballed from there.
My vision is to explain complicated question or problem in friendly way.
