Programming is just my hobby, it's not related with my job. But I think this hobby sometimes improves my working skills. Firstly I studied Java to make my program, It was not pretty but working well, at that time I realize coding is fun! After that I made some toys but it was not easy to run and show to my friends. I should install java, or eclipse -- because I didn't know deploy application at that time. anyway so I moved to Web. These day I'm interested in Node.js, MongoDB, Express.js. This is cool to run everywhere, it only need browser.
