About this Gig

"Garbage in, garbage out." No matter how advanced your machine learning models or BI dashboards are, they will fail if your underlying data is messy, inconsistent, or inaccurate.

Hi, I am an advanced Data Science student specializing in statistical modeling and data manipulation. I don't just "delete empty rows" in Excel. I use rigorous programmatic methods in Python (Pandas, NumPy, SciPy) to transform chaotic datasets into pristine, analysis-ready information.

What I can do for your data:

  • Data Wrangling & Restructuring: Reshaping data (melt/pivot), handling nested formats, and transforming raw files into clean tables.
  • Advanced Merging: Complex joins across multiple files to create a single source of truth.
  • Missing Value Imputation: I don't just drop NaNs; I use statistical methods (mean, median, mode, or predictive imputation) depending on your data's distribution.
  • Outlier Detection: Identifying anomalies using statistical methods (Z-score, IQR) to prevent skewed analysis.
  • Data Type Casting & Standardization: Fixing date-time formats, string parsing (Regex), removing duplicates, and standardizing text.

Why choose me? I treat your data with strict confidentiality. My solutions are
