Thanks for sharing your profile with us! Congrats on the recent GMAT score, that's a very strong overall score and nicely balanced between your Quant and Verbal too. Beyond that, your GPA seems strong too so I think schools will look at your academic profile very positively. It's great that you have some exposure outside India too.
Since you're coming from a technical major and an IT role, make sure that your applications demonstrate some of the "softer" skills that business schools value too...like effective communication and interpersonal skills. Since you only have 2 years of experience, be sure to highlight any leadership experience you've had - this doesn't need to be people management but can come from managing a project or new initiative at work or even from your regular volunteer work. It sounds like you're very passionate about the work you do there, so that will be great to highlight your leadership there, especially since it ties in with your long-term career goals.
The only concerns I have are that you have a bit less experience than most MBA applicants and you're aiming to make a very difficult career transition from IT to strategy consulting. It's definitely not impossible but just make sure you show that you've logically thought through those goals, why they make sense for you, and why now is the right time to make that switch.
Because of those concerns, I'd recommend adding at least one safer school to your list. I like the ones you've got but they're all of pretty similar competitiveness - though Kellogg will likely be toughest. Since you seem to be drawn to mostly east coast or midwest schools in the US, perhaps consider adding a school like Georgetown, Cornell, or Notre Dame.
Good luck with the process and keep us posted if we can help with any more questions!
