Who am I?

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.

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 today: structured, curious, calm under pressure, and focused on creating solutions that genuinely help people.

My interest in data grew from a fascination with how information can transform the way teams operate. In the military, I learned the value of clarity and sound decision‑making. In business, I learned how organizations think, move, and prioritize. Data science became the place where those perspectives came together: a way to bring structure, insight, and impact into complex environments.

I've built predictive maintenance models, developed LLM‑powered tools, and designed data products that support operational decision‑making. What I enjoy most is turning complex technical work into something intuitive and useful solutions that people actually adopt because they make their day easier.

I've learned that I thrive when I'm close to the people and processes I'm supporting. Listening to what teams struggle with and shaping data solutions that truly help them is what keeps me energized in my work.
