On Fiverr, I’ve cleaned and validated datasets for more than 100 clients, catching duplicates, missing values, and formatting errors before they reached final reports. I rebuild inconsistent spreadsheets into standardized datasets ready for analysis.

I use Excel to sort, filter, validate, and summarize client data, keeping working files organized and treating each client’s data as confidential.

For the IBM HR Analytics Dashboard project, I used Power Query to prepare employee data and built a six-KPI Power BI dashboard examining attrition. The dashboard showed a 16.1% attrition rate and traced 133 departures to R&D.

I’ve also built an Excel dashboard analyzing $1.20M in grocery sales and a Tableau dashboard tracking revenue, delivery performance, and customer ratings. I’m completing a degree in Statistics and Programming, expected in November 2026.
