The progression from developer to manager is great, especially with C-suite exposure. I'd want to dig more into your interest in consulting (it's a popular choice, so why is it a good choice for you? What skills transfer? What do you want to do long term with that consulting experience?). I agree that international experience would be great to have, especially if you're targeting INSEAD where they really value that.
In terms of academics, agree that your undergrad marks are okay. The GMAT is excellent. Already having an MBA concerns me though, as some schools are less receptive to that and some will consider you ineligible for another MBA. Even if you are eligible to apply, you must make a strong case for why you still need an MBA. Spots are competitive so they want the spots to go to not just qualified people, but qualified people who stand to gain a lot from the degree.
As far as profile improvements, it's hard to do much better on the GMAT, but I suppose if you could score higher, that could help. I also wonder whether waiting another year could help, as you're slightly on the less experienced side and another year might give you time to get some international experience (even if it was for a conference or volunteer trip). That would also give you more time away from the prior MBA and might make your case stronger. Something to consider!
