Thanks for sharing. So you've got some solid academics; some recognition and team-lead experience and work, and of course as an engineer, strong quant/analytical skills. In terms of 'strengthening your chances', generally at this point, since most of what you have done is in the past (if applying this fall), the best thing to focus on is the essays and how you'll portray yourself in the applications and interview. Brainstorming will be key-- to help you remember and then illustrate your key strengths; accomplishments; what is unique about you; what you'd contribute to a class; what you are passionate about as well as proud of. If you can identify more of those, your profile will be strengthened. You should also likely solidify your goals story a bit as well; showing you've done some thinking and are truly certain that the MBA is right for you and why.
For operations/supply chain, you could look at US schools like Tepper, Ross, Kelley, Eller etc as well.
Good luck on the process and let us know what other questions you have!
