👨‍✈️ About me

I'm a Captain in the Colombian Air Force — UH-60 Black Hawk copilot and UH-1 pilot — transitioning into data science.

My path into data began while recovering from a stroke: I started building dashboards to track my own rehabilitation — therapy, training load, sleep and recovery — and what began as personal tracking grew into deployed, tested analytics applications and a new career direction.

I bring cockpit discipline to data work: reproducible pipelines, statistical rigor, and clear communication.
