Hands-on support
I'm Head of Mid Market at Tiendanube (Nuvemshop in Brazil), Latin America's largest e-commerce platform, where I lead marketing strategy for the mid-market segment in Mexico — focused on inbound demand generation, pipeline building, and revenue alignment with Sales.
It's my third leadership role at the company in 5 years: before this I was Head of Growth Marketing (building the content & acquisition engine from scratch across Mexico and Colombia) and Head of Education for Spanish-speaking LATAM, leading the expansion of Ecommerce en Acción — the largest e-commerce education platform in Latin America.
Before Tiendanube, I led SEO/CRO at Intuit (QuickBooks Mexico), founded my own digital marketing agency specializing in e-commerce, and built e-commerce and digital marketing operations from zero in multiple companies such as Energizer, Hyundai and Daewoo — always recruiting the teams, designing the processes, and coordinating execution.
My core expertise spans growth marketing, inbound & content marketing, SEO, demand generation, marketing automation, and e-commerce strategy. I also have hands-on experience with AI tools (ChatGPT, Claude, Gemini, Midjourney, n8n) and integrate them daily into my workflows — so if you're looking to leverage AI in your marketing work, I can help with that too.
I'm a great fit as a mentor if you're: a marketer looking to level up in growth, content or e-commerce marketing; someone building or scaling a digital marketing function from zero; an entrepreneur trying to figure out their acquisition engine; or a professional navigating a non-linear career path (journalism to marketing, career pivots, moving countries — I've done it all).
I'm based in Mexico City, originally from Buenos Aires, and we can work together in English, Spanish, or Portuguese — whatever feels most comfortable.
Send me a message and let's talk about your goals. I'd love to help.
