Python Automation for Data Extraction

I’m building an end-to-end pipeline that automatically ingests raw scientific data, tidies it up, and hands back clean, analysis-ready files. The flow looks like this:

• pull in multiple CSV or Excel drops from our instruments
• consolidate and validate the incoming tables
• perform robust cleaning, transformation, and aggregation with Pandas
• write the polished output—plus concise logs—into well-named files or database tables

Performance matters because the datasets can grow quickly, so I need someone who writes modular, well-documented Python code and is comfortable using the right data-structure or algorithm to keep things fast. If you’ve previously automated data extraction, loading, and heavy cleaning tasks, you’ll feel at home here.

Deliverables
1. A runnable Python script or package (Python 3.10+) that covers extraction, loading, and cleaning steps.
2. Clear inline docstrings and a short README explaining setup, usage, and how to extend the pipeline.
3. A sample dataset processed through your code showing that the automation works as described.

I’ll review against accuracy of the cleaned output, code readability, and runtime efficiency. If that sounds straightforward, let’s automate this together.
