➤ What I can help you with
➤ Data Analysis & Reporting
Transform raw data into meaningful insights, trend analysis, KPI reports, and executive summaries that support confident decision-making.
✪ Excel Data Analysis
Clean, validate, organize, and analyze complex Excel datasets using Pivot Tables, XLOOKUP, Power Query, advanced formulas, and data validation.

Develop GIS-ready datasets, perform spatial analysis, create professional maps, digitize features, georeference imagery, and produce location-based insights using QGIS and ArcGIS.
Why clients hire me
