What I'm looking for

I seek remote or international roles leading data-driven paid media and analytics, focusing on measurable ROI, cross-functional collaboration, mentorship, and scalable growth.

I am a performance marketing specialist with over a decade of hands-on experience managing data-driven paid media campaigns across Google Ads, Meta Ads, and YouTube, directing annual ad spends above $1M and optimizing multilingual campaigns in 40+ markets.

I design and implement multi-channel strategies, automated bidding and audience segmentation, and robust analytics setups using GA4, GTM and Looker Studio to improve CPA, CTR and conversion efficiency while collaborating with marketing advisors, developers and designers.

I have led teams, mentored junior media buyers, and built reporting and tracking infrastructures for ecommerce, wellness and international clients, delivering consistent, scalable growth through creative testing, funnel optimization and cross-functional coordination.
