Ida Johnsson

First-principles thinking.
Production-grade execution.

I operate where academic rigor meets engineering reality. I don't just design models; I architect the pipelines that feed them and the APIs that serve them.

Fluent in five natural languages, I have a mind wired for syntax and structure - allowing me to master new tech stacks rapidly. I specialize in translating messy, real-world complexity into strict algorithmic logic that drives business impact.
