Additionally, as VP of Product at Total Merchant Services, she played a key role in launching their Groovv POS, and early in her career, as the CTO of Mercury Payments and one of the company’s first key employees, she oversaw comprehensive software development, IT, ISV integrations, product management, and customer service functions.
