Daniel in a few words

I’m a Data Scientist with over 6 years of professional experience. Passionate about the use of data science for process and decision-making optimization. I have a background in applied mathematics and statistics.

I help companies with my knowledge of machine learning, data analysis and visualization or any other part of the data lifecycle as I'm used to owning end-to-end data science projects. By either, making an analysis and generating recommendations or building data products (dashboards, reports, web apps, APIs and MLOps pipelines).
