I built a repeatable Python pipeline for my Instacart Grocery Operations Reorder Analysis, cleaning and loading 32.4M+ order-line records into a relational database. I used SQL to identify reorder patterns and produce merchandising and inventory-planning insights, then validated the data across five tables.

For my NFL Fantasy Performance & Opportunity Dashboard, I analyzed 29,273 player-week records in Power BI and created DAX measures to surface production, opportunity, and consistency trends. The dashboard supports fantasy roster decisions across seasons, teams, and positions.

At Amazon Fresh, I conducted inventory and pricing audits and resolved stock discrepancies using established procedures. I also answered workflow questions for a 5–6 person team and trained new associates on inventory procedures.
