Freelance Data Scientist & Machine Learning Engineer


Hey there 👋

I'm Dylan. I have over six years of experience helping businesses get value from their data.

I've delivered successful projects at organizations like Deliveroo, the Boston Consulting Group (BCG), the European Commission, and the Olympics. If you want to see what they have to say about my work, check out the testimonials on my LinkedIn profile (spoiler alert: they're all good 😉).

In my spare time, I enjoy writing – which is why I keep this blog. I've also written for popular websites such as Real Python and Hackers and Slackers. My posts have covered a wide range of topics, from data science and machine learning to financial independence.
