With a EWS Rank of 5128 in JEE Main, I believe you have quite a few good prospects among NITs, GFTIs and IIITs. Secondly, you must definitely look out for prospects in your respective Home State NIT or GFTI, incase theyre Good with strong faculty and placements. As far as your All India Options are concerned, theyre as follows

1. IIIT Nagpur, Bhopal, Kalyani, Trichy Computer, EC IIIT Pune

2. Mechanical IIEST Shibpur, BIT Mesra, PEC Chandigarh

You do have many other options including EC and Chemical, but from my perspective your best options would be CSE at IIIT Nagpur or EC at IIIT Pune. Being located in Maharashtra with Technological Hubs at Pune, Nagpur and Mumbai as well as High Tech Research Insititutes, provide a huge locational advantage and impetus to careet scope, Future Projects and Placements.
