You will get Consolidation and Standardization of Massive Data Files
Project details
I consolidate thousands of Excel, CSV, JSON, or XML files into one clean, analysis‑ready dataset—without crashing your laptop or your deadline. Leveraging Python + pandas/polars, I stream data in memory‑safe chunks, apply rule‑based validation, document every step, and deliver outputs in CSV, Excel, SQL, or Parquet. My background as a Financial Analyst means your numbers stay audit‑traceable and compliant, while my Power Query and BI skills let me hand off dashboards if you need them. Expect clear communication, reproducible code, and turnaround times measured in days, not weeks.
