I didn’t start out in tech with a clear path. Like many self taught developers, I pieced together my skills from late-night sessions, half documented errors, and an internet full of conflicting advice. What stuck with me wasn’t just the code it was how hard it was to find clear, grounded explanations for everyday problems. That’s the gap I set out to close.

Freak Learn is where I unpack the kind of problems most of us Google at 2 a.m. not just the “how,” but the “why.” Whether it's container errors, OS quirks, broken queries, or code that makes no sense until it suddenly does I try to explain it like a real person would, without the jargon or ego.
