I have a Ph.D. in CS, published dozens of papers in international journals and conferences, and wrote over a dozen IETF RFC standards. With more than 13 years of experience in various large companies (e.g., Fujitsu, Panasonic, Yahoo, eBay), I have focused on Payments in the last 9 years, in particular on software architecture, backend development, security and infrastructure. At eBay, I focus on large architectural problems, in particular in Identity and regulatory projects.
