I would like to first thank the Almighty God for all his blessings upon me and then my super mom and dad, because they really worked hard on me in the early days of my education and made me the person I am today. Also, I also want to give special thank to my beautiful wife and my two little boys for their sacrifices and moral support whilst working and building up my career in IT. Last but not least, all of my teachers, colleagues, and friends, who really helped me with their support during the whole journey and still do.
