What I'm looking for

I seek a senior growth or marketing leadership role where I can scale cross-functional teams, drive measurable revenue growth, and apply AI-driven acquisition and retention strategies.

I am a results-driven growth professional with over 15 years of experience building revenue and brand momentum through integrated marketing, demand generation, and analytics.

I have led omnichannel strategies and multi-million dollar budgets to deliver measurable outcomes, including 68% YoY revenue growth, 11.5× ROAS, and a 350% brand lift by uniting performance marketing and data-driven insights.

I build and scale high-performing cross-functional teams, create KPI dashboards and forecasting models, and implement automation and AI-driven workflows that reduce CAC and increase lifecycle conversion.

With an MBA in management and fluency in English, Portuguese, and Spanish, I combine strategic vision with hands-on execution to drive growth, retention, and sustainable ROI.
