Data Warehouse
at Scale

Stop guessing. Start trusting the warehouse.

I work as a Data Warehouse Analyst for Trendyol via Global Maksimum — large-scale analytics across CX, Fraud, Finance, and Dolap. I handle financial reconciliation, POS/payment-provider reporting, and warehouse quality practices that keep operations honest. Trust the numbers, then ship the report.

“A clean warehouse is worth a thousand dashboards.”
