What I'm looking for

I seek a data role where I can apply SQL, Python and Power BI to deliver insights, mentor junior staff, and grow into ML/AI projects in a collaborative, impact-driven environment.

I am a data professional with 2+ years of hands-on experience in data analysis, statistical modeling, and business intelligence, using SQL, Python, Excel and Power BI to turn complex datasets into clear, actionable insights.

I have practical experience across internships and lab roles where I cleaned, standardized and validated multi-year education and laboratory data, built interactive dashboards, and automated reporting to support decision-making and improve operational efficiency.

I deliver data storytelling that drives impact—improving resource allocation, optimizing pricing and inventory strategies, and uncovering funding and performance gaps for public institutions—while continuing to expand expertise in machine learning and AI.
