Martin Leung is a senior software engineer with eight years of experience building payment and Apple Pay services at Visa and now exploring hands-on product work as a "Builder" at Climbing Cat in California. He has progressed from internship to senior roles on Visa’s Apple Pay Services and Next Gen teams, combining front-end testing discipline from UC Irvine with production backend delivery.
