Turning data into decisions and campaigns into revenue

I combine deep MarTech expertise with hands-on campaign management to drive measurable business outcomes — connecting online and offline revenue across D2C, retail, and app channels, from MarTech integrations and data warehousing to AI-automated reporting.
