Hi

Unfortunately, you cannot get any NIT/ IIIT/ GFTI through this rank of yours in JEE Mains 2019. Your AIR is too high. Not only that you would not get even the North-East NITs if you do not have a Home State Quota there. 

But definitely you can try for Private Colleges through their own private counselling.

Best of Luck.

Hope this helps.

Cheers!
