Instructor Details

Samuel Okon

Hi! I’m Samuel. I have a degree in Industrial Chemistry from the Federal University of Technology, Akure, and you might call me a bit of a data geek.

After getting into data analytics just for fun, I quickly discovered that it wasn’t just interesting — it was also a highly valuable career path. I left my science background behind and fully embraced analytics, and I haven’t looked back since.

I’m passionate about teaching people how to make sense of data. That’s why I created this course — to help beginners and non-technical professionals feel confident working with Excel, SQL, and Power BI.

You wouldn’t believe how empowering it is to truly understand your data. Sign up and see for yourself why so many learners are building data skills to grow their careers. I genuinely believe this course gives you everything you need to get started — and if you don’t agree, I’ll happily refund your money.

Join me in this data adventure — I can’t wait to see what you’ll discover.

The instructor is very slow in speaking and not very clear. gets confused while explaining.
