AI systems & data engineering

Building intelligent
systems from
raw data.

I'm a Data Science undergraduate who works across the full stack of a model's life — forecasting, explainability, business intelligence and the engineering that gets a system into production.

About

I'm a Data Science undergraduate building systems that sit at the intersection of machine learning, analytics and software engineering — not just models that score well in a notebook, but tools that hold up once they're deployed.

That's taken me through AI forecasting systems, explainable machine learning, cybersecurity analytics, business intelligence dashboards, and a handful of local engineering tools built because I needed them myself.
