Who am I?
Yo, I'm Tochukwu, a Frontend Developer with a passion for crafting clean UIs and smooth interactions. I'm all about mind-growth, weird, and mystery books, but coding keeps me up more than late-night page-turners. My browser tabs? A wild mix of docs, Stack Overflow, and book summaries I'll totally finish someday. I thrive on challenges, lose sleep over bugs, and live for that moment when the code just works. Let's build something dope together.
