Hello!

I am Febriyan Ahza — a programmer who build systems that work, and I care deeply about how they work. Most of my time goes into distributed systems, networking, and the kind of foundational problems where you need to think carefully about what happens when things inevitably break or scale. I also lean toward the mathematical abstractions underneath — category theory, machine learning theory — not because they're fancy, but because they often reveal the obviously correct way to structure a solution.
