About me

Professional with six years of experience in software engineering. Graduated in Computer Science Engineering (bilingual degree) from Universidad Carlos III de Madrid and Master's in Data Science from the Universitat Oberta de Catalunya. I'm passionate about data end-to-end: from the architecture, ETL processes and big data that sustain it, to machine learning and business analytics that turn it into decisions. And especially the latest advances in generative AI. Today I develop AI pipelines, build and deploy production applications, and leverage AI in the development process itself to multiply productivity.
