What I'm looking for

I seek a role where I can lead data-driven paid social and CRO initiatives, collaborate cross-functionally, scale campaigns, and implement measurement and automation to drive measurable growth.

I am a strategic digital marketer with experience driving audience growth and revenue across nonprofit, tech, and media sectors through paid social, CRO, and marketing automation. I have led end-to-end campaign execution, rebuilt measurement stacks (GA4/GTM + Consent Mode), optimized landing pages, and implemented HubSpot automations to improve conversions and streamline lead capture.

I combine creative storytelling with data-driven decision making to scale performance across channels, delivering results such as a 25% increase in form submissions, a 5x increase in lead generation for clients, and substantial CPL reductions through structured A/B testing and optimization. I collaborate closely with stakeholders to align UX, content, and campaign objectives toward measurable business impact.
