Hey !
Yeah you can.
A full time masters degree in computer science can take up to 15 months or more, on the other hand part time masters degree can take you anything between 24 months to 36 months.Your newly acquired knowledge and skills can put you at an advantage in the company you are working for. And it is always good to earn and learn at the same time, though you may have some hectic schedule.. managing your work can leave you at greater heights.
Hope this helps
All the best !
