CV
I work with business data and data visualization in Tableau. I help transform large datasets from Excel, CSV files, Google Sheets, and databases into clear analytical reports and interactive dashboards.
My main focus is data preparation and cleaning, combining data from multiple sources, KPI calculation, performance analysis, and creating visualizations that support business decision-making.
For data processing and analysis, I use Excel, SQL, and Python (Pandas). For data visualization, I use Tableau.
I have practical experience delivering analytical projects for the agricultural and energy sectors, including the development of interactive dashboards for solar power plant performance and enterprise energy consumption analysis.
I am responsible, detail-oriented, meet deadlines, and focus on creating analytics that provide practical value for clients.
