Hi, I'm Toochukwu (TC) Okolie.

I started I Know Database because I believe databases are the most underappreciated skill in software. Every application you use sits on top of one — but most developers treat them as a black box.

My goal is to change that. Through articles, videos, podcasts, and structured courses, I want to make database knowledge accessible to everyone: the complete beginner hearing the word "database" for the first time, the working programmer who wants to make better architectural decisions, the student preparing for exams, and the researcher tracking the frontier.

Everything I publish follows one principle: explain it so clearly that it sticks, and so deeply that it's actually useful.
