Your first step is to focus of your studies and decide on a specialization within IT, Finance, Business, etc and a domain under that.
To decide which degree program to pursue, look closely at your individual skills and aptitude, as well as the personal satisfaction and enjoyment you get when you study a particular topic. You can also look at common career paths taken by various program graduates to see which of them feel right for you.
Then go for masters. Just because you finished working for 1 year experience do not jump into masters. Its a slow process of selecting the required domain/ technology , university, course fee and its structure.
Hope you can take your choice now.
