Testimonials from participants

The 5-day workshop Data Science with R gave us a glimpse of the possibilities that R has to offer. During the workshop we got to work on actual current projects under the supervision of Jeroen, which was very insightful. Jeroen gave us a lot of practical examples and tips. We’re not quite there yet, but Data Science Workshops gave us a head start!

Arjen Verhulst
Analyst at Gemeente Nijmegen

I learned a lot from the in-company workshop on Programming in Python, and thought it was great that Jeroen could improvise around our specific learning needs and thus offer exactly what we wanted to learn without making it too difficult. Also, it was really useful to see what different solutions there were for an exercise, and what was and wasn’t “good” about it—that’s exactly something which is difficult to pick up with self-study.

PhD Candidate at Huygens ING (KNAW)

The Anomaly Detection masterclass by Jeroen provided us with very useful tools to address business issues where (early) detection of anomalies is of the greatest importance. Consider, for instance, early detection of DDoS attacks, credit fraud or insurance fraud. Recommended!

Rik Kleine
Data Science Consultant at KPN ICT Consulting

Great workshop! Very well done and very useful information delivered in an excellent and interactive manner. Jeroen anticipated very well on the different knowledge levels within the group. I would highly recommend the Data Science at the Command Line workshop to anyone that is interested in either kickstarting their command-line experiences or improving their data science with Unix power tools.

Data Scientist at Teradata

At Brabant Water, most of us were still using spreadsheets to clean, analyse, and model our data. Thanks to Jeroen, who delivered an engaging, hands-on workshop at our office, many of us have switched to Python and Jupyter Notebook, which allows our analyses to be much more advanced and reliable.

Attending the bespoke course Data Munging with Pandas at Textkernel has proven to be an excellent choice. Jeroen’s personal approach and highly interactive way of teaching made this course valuable to a diverse group of developers and analysts, as did the possibility to apply theory on our own data and API during the courses. I’ve since been able to code cleaner and more efficient, and applied the pandas package in several monitoring and analytics scripts.

Data Quality Analyst at Textkernel

Data Science Workshops organised a training at the Xomnia office in Amsterdam about web scraping using R and the rvest package. We acquired all the knowledge and skills required to successfully bring theory into practice. In addition, this training inspired me to get the most out of R by using the various packages from the Tidyverse.

Boris Stapel
Trainee Data Scientist at Xomnia

Even experienced data scientists need to keep working on their skills and knowledge. For the past half a year, Data Science Workshops has come to our office once a month, to teach us about a variety of topics, ranging from NoSQL to t-SNE. This is a great way to stay fresh and look beyond the tools and techniques that you’re already familiar with.

Testimonials from managers

Jeroen organised for KPN a ten-week course on Data Science with R. The combination of training, on-site coaching, and remote support ensured that our analysts are applying the new knowledge and skills in their daily projects. For instance, they’re now capable to implement complex predictive models using R. We’re looking forward to the follow-up course on Advanced Machine Learning.

Manager Commercial Analytics at KPN

Data Science Workshops facilitated a data hackathon for the data team of Transavia. They made sure it was inspiring, helpful, and leading to valuable insights in the way of working with Python for multiple projects and analyses that Transavia is currently implementing.

Charles Verstegen
Head of Partner Sales and Data & Analytics at Transavia

We received a personalized coaching session from Jeroen and this was very valuable to me. It’s such a skill to correctly estimate the level of the participants, but this was rightly done and the training was perfectly adapted to our needs. Our training had a practical focus and we could use it as a starting point for the rest of our work. This training provided us with the tools and way of thinking to perform the data analyses independently.

Mirthe Groothuis
Project Lead at Dutch Institute for Clinical Auditing

Besides demonstrating a good knowledge and experience in command-line tools for data science, the instructor had very good training skills, clear communication, and managed to adapt the level of the training to the level of the audience, which is not always easy!

Marc Canaleta
CTO at Social Point

Our DataLab team enjoyed a three-day PySpark course from Jeroen. Jeroen’s approach is personal and professional. I recommend Data Science Workshops to anyone in the field of data science.

Laurens Koppenol
Lead Data Scientist at ProRail

Data Science Workshops was able to skillfully differentiate, addressing various Unix Consultants at Snow with very different skill sets. Jeroen made some people rise above themselves.

Joost Helberg
CTO at Snow

Our Insight & Analytics team followed a five-week course in R provided by Jeroen. The training was built around our own data and challenges and therefore was easily applyable in our daily business. The atmosphere during our training days was always very pleasant and everybody looks back on a very succesful training.

Yannick Jacobs
Manager Insight & Analytics at DPD

Before the six-day workshop with Data Science Workshops, our team of engineers only had some theoretical knowledge of data science and we primarily used costly tools such as Tableau to do data analysis. However, after four days of interactive hands-on sessions with Jeroen, we were able to use Python, our preferred programming language at eHealth Africa, to analyse our data, create some amazing visualisations and even start making machine learning predictions. We moved from theory to real application in a very short period of time, making this workshop extremely valuable. I highly recommend Data Science Workshops.
