He used to have biography here Smile | :) , but now he will hire someone (for free offcourse Big Grin | :-D ), Who writes his biography on his behalf Smile | :)

He is Great Fan of Mr. Johan Rosengren (his idol),Lim Bio Liong, Nishant S and DavidCrow and Believes that, he will EXCEL in his life by following there steps!!!

He started with Visual C++ then moved to C# then he become language agnostic, you give him task,tell him the language or platform, he we start immediately, if he knows the language otherwise he quickly learn it and start contributing productively

Last but not the least, For good 8 years he was Visual CPP MSMVP!
