About Belén

I'm a Senior Product Manager with 5+ years building consumer-facing products in marketplaces, ecommerce, and logistics, close to the user, focused on measurable impact.


At Mercado Libre, I led Seller Experience across 5 countries: building tools that reduced shipping delays by 10%, cut logistics inefficiencies in half, and helped thousands of sellers grow their businesses. That's the kind of work that energizes me, when a product decision has a direct, visible effect on real people.


I'm now looking for roles where the mission matters. Companies tackling waste, extending the life of products, making sport or education more accessible, that's where I want to invest my energy.


On the side, I'm co-building an AI-powered platform that helps people in Spain make better car-buying decisions through personalized recommendations and real market data. It's kept me close to early-stage discovery, fast iteration, and the full product lifecycle from scratch.


Technically comfortable (SQL, analytics, API-driven systems), but my biggest value is connecting user problems to business outcomes and building the alignment to act on them.



Outside of work, I experiment with biomaterials: creating alternatives to plastic from organic waste like fruit peels and natural binders. They biodegrade in months, cost almost nothing, and start from zero: just curiosity, iteration, and a lot of failed prototypes. It's the same mindset I bring to product: identify a real problem, test a cheap hypothesis, learn fast. Sustainability isn't just a sector I want to work in. It's something I actually do on my kitchen table.


If you're building something with purpose in sustainability, second-hand commerce, edtech, or sport, I'd love to connect.
