Ecommerce Account Management Specialist
John Krell Sta Ana
Partnering with Brands to achieve Growth through Innovation and Collaboration
Full-stack e-commerce specialist who can list, ship, and drive traffic. I run Amazon or Walmart end-to-end, launch Google & Meta campaigns, and build internal tools with agentic AI. I double as a domain expert and project manager: defining specs, running sprints, and writing the playbook so the next run is twice as smooth.
