About

Hi there! I’m Maria Josefina David, a results-driven Paid Media Manager with hands-on experience across Meta, Google, TikTok, and DV360. I design and optimize multi-channel campaigns for e-commerce and lead generation, translating data insights into scalable growth. I thrive in fast-paced agency environments and love turning complex analytics into clear, actionable strategies.

I collaborate closely with clients to refine messaging, creative direction, and audience targeting, always aiming to improve ROAS, reduce CPA, and drive full-funnel growth. When I’m not optimizing campaigns, you’ll find me mapping out data-driven plans that translate into tangible business results for brands across Latin America and beyond.
