Summary

With over 12 years of experience driving user and business growth at the intersection of SEO, product development, and strategic execution. My background spans agency, startup, and enterprise environments — including high-impact roles at eBay and Adevinta — where I’ve consistently turned organic acquisition into scalable business outcomes.

With a strong foundation in technical SEO and a product-led mindset, I specialize in leading cross-functional teams, aligning stakeholders, and designing roadmaps focused on the entire AARRR funnel. My approach combines experimentation frameworks, user insights, and agile project management to prioritize initiatives that drive measurable impact.

Beyond in-house roles, I’ve co-founded an AI-powered SEO SaaS startup, built and scaled SEO and product teams, and contributed as a mentor and speaker at international events. I also teach at top business schools such as ESIC, IEBS, CEF, and EADA, training future professionals in digital strategy and growth.

I thrive in fast-paced, cross-functional environments where product, data, and marketing converge — and I’m always looking to tackle complex growth challenges through structured execution and continuous iteration.
