Engineering Clarity in the Age of AI

Notes from two decades of building systems. What worked. What did not. What I am still figuring out.

Kunwar "AKA" AJ

I have been building systems for over two decades, mostly behind the scenes. This is me finally sharing what I have learned - what worked, what did not, what broke spectacularly. Not claiming to have all the answers. Just sharing my journey in case it helps someone else avoid my mistakes.

What You Will Find Here

I write about the decisions that keep me up at night. The architecture choices that seemed right at the time. The failures that taught me more than any success. The patterns I have seen work across different projects and teams.

This is not a place for step-by-step tutorials. There are plenty of those already. I am not chasing the latest trends or trying to sell you anything. I am simply writing down what I have learned, in case it helps someone else who is wrestling with similar problems.

If something resonates, that is great. If you disagree, I would love to hear why. That is how we all get better.
