  As of January 2019, I've joined Conexxus full-time. The LinkedIn timeline shows 14 years, which is correct, but that includes my work on behalf of Verifone as a Conexxus member. New Initiatives at Conexxus are an exciting place to be! Conexxus has written many successful "semantic" standards in XML (called "NAXML").

Conexxus has written many successful "semantic" standards in XML (called "NAXML"). Our new initiatives include converting XML to JSON and adding APIs. The technology has moved on, and continues to do so. But the reasons for having industry standards endure - aggregate time to market, better choice options for retailers, freedom from "reinventing the wheel" for suppliers, lower total cost for all, and lower technical debt. We're in the process of trying to make great choices to boost the API Economy for Fuel and Convenience Retail.
