At İstanbul Technical University, I supported academic research by collecting, cleaning, and validating datasets, then using Excel and SQL to prepare analysis-ready information. I also prepared reports, presentations, and visual summaries of technical findings.

For my SQL Data Warehouse Portfolio, I designed a Bronze–Silver–Gold workflow concept to integrate CRM- and ERP-style data. I structured a Gold-layer star schema with fact_sales, dim_customers, and dim_products, and applied SQL transformations and validation logic to prepare reporting views.

In my SQL Data Analytics Portfolio, I analyzed business KPIs, customer segments, product performance, rankings, and trends. I used SQL queries to compare and rank results, and developed customer- and product-focused views.

My engineering projects also include an Excel-based open-pit lignite project model with financial evaluation and sensitivity analysis, and an iron ore mine-planning project using Micromine. I bring a quantitative engineering background and am developing my Power BI skills.
