About

Professional summary

I am a performance marketing strategist with five years of experience driving creative strategy, paid media optimization, and data-informed decision-making across high-volume e-commerce and B2B brands.

I specialize in translating performance signals such as CTR, ROAS, hook rate, CPM, CPA, and conversion data into practical creative direction. I combine analytical rigor with a creative background in photography to develop effective visual and messaging strategies.

I have led multi-brand creative testing across Meta, TikTok, Google, and Bing, managing audience strategy, segmentation, creative briefs, asset workflows, performance analysis, and stakeholder reporting.

I developed proprietary testing approaches, including Hybrid Predictive Angle Scoring and micro-persona testing frameworks, to prioritize high-potential creative angles and improve campaign efficiency through iterative experimentation.

I am experienced in analytics, attribution, reporting automation, dashboard development, and cross-platform tracking accuracy. My work has contributed to measurable improvements in CTR, CPA, reporting reliability, and strategic visibility.

I enjoy collaborating with creative, compliance, finance, and client teams to balance growth objectives, brand positioning, regulatory requirements, and measurable acquisition outcomes.
