Profile Evaluation for 2017 Admit

Hi Grandmaster,
You've got a lot of good stuff here -- strong professional experience, super GMAT, excellent GPA. Missing for me are a clearly-stated leadership path and any international exposure. I'd want to see both of these before I could assess your chances more clearly.
Goals: frankly I'm not wild about tech as a goal for you, simply because your experience seems to be elsewhere and you'll be competing against a lot of people who already do nothing BUT tech. So unless I am misreading your professional background, these goals put you at a competitive disadvantage in terms of admittance (others might differ with me on this).

What I'd recommend between now and your applications next year:
1) Show your international exposure clearly, in your resume and in any discussions about your background. Global vision is paramount in top MBA programs.
2) Increase your extracurricular leadership: tutoring and board membership are relatively common roles for young professionals, so team or group leadership would add more value. I'd recommend sticking with the organizations you already have ties to, but expanding into a team leadership role, ideally recruiting and leading volunteers -- perhaps bring in some colleagues from your workplace to do mentorship days?
3) Rethink your goals. Haas had a terrific "goals" question in 2014; take a look at the wording of that question and think about the issues that would raise: Who will hire you post-MBA, and in what role? How is your background compelling to this company? What is something you would do better for this company than any other employee?

The good news here is that all the action items are in your hands -- with some tweaks in your current path and presentation, you should do very, very well in applications to top business schools next year!

Good luck,
Margaret Strother
