I turn messy data into decisions people can act on. I care about the math under the hood and the story it tells — because models that can't be explained don't get used.
I'm a data scientist with a genuine interest in how things work — not just the models, but the people, decisions, and systems around them. I've worked on everything from exploratory analysis to predictive modeling and ML pipelines.
Before I was writing code, I was asking "why?" — and that habit stuck. I think the best data work is skeptical and human: rigorous enough to trust, honest enough to be useful.
Outside the terminal I'm probably reading, making coffee, or thinking about a problem I haven't solved yet.
