The DIY Data Scientist is a weekly newsletter sent out each Saturday morning to thousands of professionals wanting to build real-world, do-it-yourself (DIY) data science skills for the AI-driven future of business.
The newsletter is structured around hands-on tutorials on the skills that I’ve used for years as a data scientist for previous employers and in my current work as a data science consultant and educator.
Tutorials include Python code and data so you can follow along and experiment to build your skills.
You can access past newsletter issues here, organized by the various tutorial series.
