Turkey

Message

At DenizBank, I build and maintain performance reports used by investment managers and senior executives to track investment advisor results.

I query datasets of up to 2M+ rows with SQL and design Power BI dashboards that turn complex data into KPI visuals for senior management.

Previously, as a Sales Planning Assistant Specialist at CK Energy, I monitored KPIs and analyzed sales performance to support planning and management decisions.

At Şekerbank, I managed a commercial customer portfolio and met sales targets while promoting banking products and services to business clients. My Industrial Engineering background and reporting experience support my work in data-driven sales analysis.
