My name is Hugo. I am a data specialist from Utrecht, The Netherlands and I have
over 10 years of IT experience.
I love to wrangle and munch data to extract
insights that are hidden underneath its surface. My favourite tools
include SQL, JavaScript, D3.js and
Java, but I am also comfortable with Python and R.
Throughout this page you'll find some examples of data visualizations in D3.js. For more projects, have a look at my Github repositories, or visit my LinkedIn profile for more details.
Data Science is the extraction of knowledge and actionable insights from large volumes of structured and unstructured data.
Combine raw data from a variety of sources, both internal and external, and ingest it into a suitable data processing environment.
Fill missing values, normalize and infer new features to create a clean and enriched data set. Plot exploratory figures to get to know the data, find outliers and anomalies, and identify potential predictors.
Gain a deeper understanding of the data and apply suitable models to learn the message that is hiding in the data. Validate the model and verify the hypothesis.
Prepare intuitive, visually appealing content that summarizes the lessons learned and, most importantly, tempts users to take action.
