I'm Ananda Affan Fattahila

I work as a Golang/Rust & React Ecosystem in the finance world. I write to make things meaningful — solving real problems while keeping them easy to evolve.

Engineering DepthComplex Thingsmade easy to change

I decompose complex architectures into malleable mental models that resist rot and embrace evolution.

∫ |Ψ|² dV = 1
∇ × E = -∂B/∂t
HΨ = EΨ

Context

Master the environment where your code lives and evolves.

∫ |Ψ|² dV = 1
∇ × E = -∂B/∂t
Δx·Δp ≥ ℏ/2

Clarity

Strip away the noise until only the essential remains.

∫ |Ψ|² dV = 1
∇ × E = -∂B/∂t
S = k ln W

Actionable

Turn abstract concepts into concrete architectural wins.
