If your numbers don’t tie out, your inventory doesn’t match, or your reports can’t be trusted - I fix that. I build clean, reliable data systems that help businesses understand where their money, inventory, and operations actually stand. My work has identified $100K–$500K+ in hidden waste, reconciled broken financial reports, and replaced fragile spreadsheets with structured, repeatable systems. What I Do I specialize in solving messy, high-impact data problems across finance and operations, including: • Financial data reconciliation (transactions, GL, reporting discrepancies) • Inventory analysis & discrepancy detection across systems (store, warehouse, 3PL) • Spend analysis (P-cards, vendors, anomaly detection, policy compliance) • Excel system builds (not just spreadsheets but structured, scalable tools) • SQL-based data extraction and reporting • Dashboard development (Power BI, Qlik, Tableau, SAP Analytics Cloud) What Makes My Work Different Most analysts stop at “here’s the data.” I go further: • I make sure the numbers tie out to the source system • I document transformations so results are repeatable and auditable • I design outputs that are actually usable for decision-making This is especially important for: Finance teams Operations teams Audit / compliance environments Selected Project Experience • Identified ~$600K in unnecessary telecom spend by analyzing 8,500+ devices, leading to immediate cost reduction actions • Reconciled discrepancies between financial reporting outputs and SAP data (GLT0, BSEG), correcting multi-million dollar misinterpretations • Built a full P-card analytics system (2017–2025) to detect anomalies, vendor patterns, and high-risk spending behavior • Developed structured Excel-based systems for tracking, reporting, and operational decision-making Tools & Platforms Data & Analysis: Excel (Advanced), SQL, Python (Pandas), Alteryx BI & Visualization: Qlik Sense, Power BI, Tableau, SAP Analytics Cloud Systems & Data Sources: SAP (ECC, S/4HANA), Concur, financial and operational systems How I Work I focus on clarity, speed, and trust: • I ask the right questions upfront to avoid rework • I communicate clearly and keep things moving • I build solutions that you can actually maintain after handoff If you’re dealing with messy data, inconsistent reporting, or systems that don’t quite add up - I’d be happy to help.
