What I'm looking for

I seek a role where I can apply SQL, Python, and visualization skills to deliver operational transparency and data-driven decisions, collaborate with leadership, and continue learning.

I am a data analyst experienced in the full data lifecycle, from data cleaning and modeling to visualization and forecasting. I use SQL for querying large databases, Python for wrangling and forecasting, KNIME for cleansing workflows, and Tableau and Excel for compelling, actionable reporting.

I have delivered static and ad-hoc reporting, built workflows to transform public and organizational data, and supported commodity pricing analysis across U.S. and U.K. operations. I helped construct data infrastructure for transportation, optimizing trucking, barge lanes, and rail to increase transparency and efficiency.

My background includes client-facing roles and collaboration with senior leadership, including reporting directly to depot admins, the COO, and heads of departments. I take pride in translating complex datasets into digestible visualizations and models that drive better decisions.

I am sociable, eager to learn, and focused on bringing efficiency and clarity to teams through automation, advanced Excel techniques, and well-designed dashboards that improve bidding, pricing analysis, and operational transparency.
