Tracey Weber, North America head of Internet and mobile banking at Citi, is leaving the banking giant at the end of June to pursue new opportunities.

During her nearly three years at the company, Weber oversaw development of the Citibank for iPad app, the overhaul of Citibank Online experience, and new mobile offerings, such as PopMoney and mobile check deposit. In June 2012, she was awarded “Mobile Banker of the Year” by Bank Technology News.

Succeeding Weber will be Melissa Stevens, a 15-year Citi veteran who most recently was director of the global digital banking program and head of global Internet product management. She has also held positions across the bank’s global consumer businesses and in Citigroup’s Corporate Center.
