Léslie Costa

I’m a Marketing and Advertising specialist focused on strategic account management and results in full-funnel campaigns, bridging branding and conversion across complex ecosystems like Amazon DSP, Mercado Livre, and iFood. I’ve delivered measurable impact, including an average 19% ROAS increase and consistently exceeding revenue targets in major marketplaces.

In my current role as Growth Media Analyst II, I lead strategy and implementation for Retail Media campaigns on Mercado Livre and Amazon, managing client targets through iFood Ads and Daki Ads with weekly optimization and daily budget/pacing control. Previously, as a Programmatic Media Analyst II and Media Executive, I managed programmatic delivery across multiple accounts, built Enhanced Brand Content (A+) briefings, and produced insight reporting using KPI analysis, conversion attribution, and measurement to guide stakeholders.
