With a career spanning ad-tech, enterprise software, e-commerce, and STEM research, Zach brings a rare combination of engineering depth and strategic oversight.
Before founding ZDN Enterprises, LLC, Zach served as Technical Lead at Bandsintown Group, where he worked on Tonefuse, a contextual ad platform reaching millions of users daily.
