[ About Me ]

The person behind the data.

I am a freelance Data Scientist who combines a business mindset with military-shaped discipline to build data products that support clear and confident decision-making.

01

Background

Before I ever wrote my first line of Python, I studied Business Management and trained as a military pilot. Those two worlds couldn't be more different, yet together they shaped how I work: structured, analytical, and focused on clarity in environments where decisions matter.

My path into data started with a fascination for how the right information can transform the way teams operate. In the military I learned discipline, precision, and the value of reliable information. In business I learned how organizations think, adapt, and make trade-offs. Data became the place where those perspectives came together.

Today I build data products that help teams make confident decisions, from predictive maintenance models to LLM-powered tools and operational dashboards. I enjoy translating complex technical work into solutions that feel intuitive, practical, and genuinely useful.

What energizes me most is working close to the people I support: listening to what they struggle with, understanding their constraints, and shaping data systems that make their work easier. That's where I do my best work.
