👋 Hi everyone, I'm Ognev Robert Precious.
I've been on a journey to learn data science since 2021. It wasn’t until last year that things finally started to click. Since then, I’ve been working through projects, mostly using Kaggle datasets, and building up my understanding through practice.
This blog is where I share everything I’m learning — from hands-on tutorials to projects I’ve solved, and how I approached them. I’m also a neuroscientist, and I love making learning feel approachable and engaging. Sometimes, when I find a topic hard to understand on the internet, I rewrite it in a way that makes sense to me. That’s what you’ll find here: a learning space built around curiosity, clarity, and personal growth.
Let’s keep learning together!
