Sin’s MBA Qualifications

I’m an HBS MBA and former product leader at Tesla and Rivian, where I built and led complex systems at the cutting edge of tech and sustainability. I didn’t come from a target school or a cookie-cutter background—I earned every step by learning fast, delivering results, and telling my story with impact. Now, I help others do the same. Whether you’re applying to top MBA programs or navigating what comes after, I bring sharp, honest feedback, real-world insight, and a clear strategy to help you stand out and succeed.
