Alfonso Guisado González

I am a Statistician and Data Scientist passionate about Big Data, Predictive Modeling and Machine Learning. My ambition is to transform data into knowledge and build models that not only predict but also make a real impact on decision-making. My approach combines statistical rigor with the practical implementation of advanced data science techniques, always advocating for readable and clean code. I am constantly striving to learn new technologies and share my journey with the community.
