Hello my friend, your ranking in JEE Mains appears to be quite good but unfortunately this ranking is of no use for seeking admission in any IIT. For getting admission into IIT student needs to appear for and pass with good marks JEE advanced entrance examination. If you had appeared for this and got a good ranking then you have chances of getting admission in any of the IIT. For the branch of CSE, student needs to be in the top bracket of percentile then only has some chances.
Best wishes to you.

Hello RK, if I may say so you have obtained the rank which is a bit on the lower side. There are approximately 50K seats on offer. 10% EWS quota means about 5K seats but your ranking in EWS too is about 13K. But do not loose hope. Admission process throws up many surprises. To help you I am attaching a link that will predict the branch and the college that you can get based on your performance in JEE Mains. https://www.shiksha.com/engineering/jee-main-college-predictor
