About me
I am an Excel Super User and Senior Data Analyst with an MBA and 10+ years of experience turning complex, broken spreadsheets into clean, user-friendly tools. My strengths include building dynamic Excel and Google Sheets dashboards with automated reporting logic, data validation, interactive dropdowns, and robust formulas (VLOOKUP, INDEX/MATCH, COUNTIFS and Pivot Tables) to eliminate manual entry and prevent errors. I can also perform deep dives into raw operational data to fix structural formatting issues, trace process bottlenecks, and model historical trends.
