About

As the Vice President of Technology and Operations at Visa, I lead global teams to drive technological innovation and operational excellence in the payments industry. My role involves strategizing and implementing solutions that enhance Visa's technology infrastructure and operational capabilities, ensuring seamless and secure transactions for millions of users worldwide. Previously, I served as a Partner Director of Engineering at Microsoft, where I was instrumental in elevating Microsoft Sports from the #4 to the #1 sports destination on desktop worldwide between 2019 and 2021. I also spearheaded the acquisition of Smash.gg, the leading esports tournament platform in the United States at that time. Additionally, I contributed my expertise as an Advisory Board Member at Stripe, providing strategic guidance in the evolving payments landscape. I hold a Master of Science degree from the University of Washington, graduating with honors in the top 10% of my class. Expanded my executive education at the MIT Sloan School of Business and was honored as an International Fellowship recipient in 2016. In the realm of competitive programming, I am a two-time ACM ICPC South American Runner-Up and a Programming Contest World Finalist. My passion for research led to receiving the Best Service Computation Paper award in 2015, and I have published multiple papers with IEEE. I am an inventor with over 60 patents. At Microsoft, I played key roles as a member of the WebXT Patent Leaders Committee and the WebXT Interview Process Committee. My passion to algorithms and coding extends beyond my professional life as a hobby. I maintain a top 100 programming blog (https://anothercasualcoder.blogspot.com/), where I share insights and algorithms. On LeetCode, I have solved over 1,700 problems, ranking in the top 0.3%, and I am among the top 0.5% of problem solvers on ProjectEuler.net. I love math books, algorithms and sports.
