What I'm looking for

I seek a collaborative role where I can use SQL, Python, and visualization to improve decision-making, optimize operations, and grow professionally.

I am a results-driven data analyst with hands-on experience across the full data lifecycle: SQL querying, Python wrangling and forecasting, KNIME workflow construction, advanced Excel modeling, and Tableau visualization. I have delivered static and ad-hoc reporting, built data infrastructure for transportation and logistics, and partnered with senior leadership to inform pricing and operational decisions.

My background spans recycling commodities, construction estimating, and digital marketing for startups, where I increased social engagement and built analytic workflows that improved transparency and efficiency. I am sociable, eager to learn, and focused on producing digestible, high-impact analyses that drive business outcomes.
