Hi, I’m Jeffy — a data analyst with an MSc in Data Science and hands-on experience working in London. I’m passionate about turning raw data into clear, useful stories that actually help people make better decisions.
I created Data with Jeffy as a space to share what I learn along the way — practical SQL tips, Power BI and Tableau walkthroughs, career insights, and honest reflections from someone who’s been in the trenches of real-world analytics.
Whether you’re just starting out in data or looking to sharpen your skills, you’ll find content here that’s straightforward, jargon-free, and built around genuine experience.
No fluff. Just data — explained like a friend would.
