Why Hire Me as Your Data Scientist & AI Engineer

Most businesses don't have a data problem, they have a decision problem.

I work with founders, marketing teams, and operators who sit on large amounts of data but struggle to turn it into clear, confident decisions. My role is to bridge that gap using data science and applied AI.

Over the last 4+ years, I've helped teams understand why revenue dropped, identify which customers actually drive growth, and pinpoint where automation delivers the highest ROI, not by throwing models at the problem, but by starting with the right business question.

I design practical machine learning systems, analytics dashboards, and AI tools that fit into real workflows, ship to production, and deliver measurable outcomes.
