I’m an e-commerce growth strategist with 15+ years of experience in paid media, SEO, and conversion optimization. I have a proven track record of exceeding ROAS targets for DTC and B2B clients, including global brands, SMBs, and startups. I’m currently pivoting into AI-driven e-commerce tools, applying hands-on knowledge of campaign mechanics, product feeds, and customer behavior to contribute to AI product development, marketing, or strategy roles.
I excel at turning data into actionable growth plans, building scalable acquisition funnels, and optimizing conversion paths across paid search, shopping, social, and organic channels. I enjoy collaborating across teams to design outcomes-driven experiments and leverage AI/automation to improve performance at scale.
