I'm Ichi, and I write blog posts about Data Analysis using SQL, R, and theories in Applied Mathematics (made easy).
I started my career way back in 2012, and while the tools have changed over time, the purpose of Data Analysis is still the same. We analyze data to give meaning to our data.
I believe that learning is best done through experience. Right after reading a topic, I go out and apply it on a real-world problem, no matter how simple it may be.
