Combining creativity
& digital strategy

I'm a Growth Manager with over 8 years of experience in digital marketing, specializing in the Fintech and Blockchain sector. My approach combines creative strategy with technical skills to drive user adoption and scale digital products.

Currently leading growth at Criptan, one of Spain's most important crypto platforms, where I manage acquisition and retention strategies using Big Data and on-chain analytics to optimize results in real-time.

I also lead the adaptation of communication and acquisition strategies to the new MiCA/CNMV regulatory framework, and integrate generative AI tools into marketing workflows to optimize content production and data analysis.

My passion for blockchain technology and the Web3 ecosystem drives me to always stay at the forefront of digital innovation.
