About this Gig
As an Electrical Engineer and Data Science Fellow, I provide engineering-grade precision to your datasets. Whether you have "dirty" CSVs, broken Excel sheets, or PostgreSQL database errors, I ensure your data is accurate and ready for use.
I don't just move data; I validate it using professional frameworks like Medallion Architecture.
What I offer:
- Deep Cleaning: Removing duplicates, handling missing values, and fixing formatting using Python (Pandas).
- Database Setup: Creating optimized tables in pgAdmin/PostgreSQL with proper Primary Keys and data types.
- Error Resolution: Fixing "extra data after last expected column" and common import/export bugs.
- System Validation: Ensuring data follows logical rules and business constraints.
- Automation (Premium): Python scripts for recurring cleaning tasks.
Why hire me?
- Engineering Mindset: Rigorous, systematic approach to data integrity.
- Tool Mastery: Expert in SQL, Python, and Google Colab.
- Reliable: High-precision results delivered on time.
Please contact me before ordering for custom requests. Lets clean your data!

FAQ
What file formats do you work with?
I primarily work with CSV, Excel (.xlsx, .xls), and SQL dump files. I can also process JSON or unstructured text logs if needed for more complex technical data.
Is my data kept confidential?
Absolutely. As an Electrical Engineer, I treat data with the same professional ethics as any engineering project. I am happy to sign an NDA if required, and I delete your files from my local system once the order is completed and approved.
Do you provide the Python scripts you used?
Standard cleaning is delivered as the final clean file or SQL import. However, if you select the Premium package or the "Script Delivery" gig extra, I will provide the fully commented Python (.py or .ipynb) script so you can automate the process in the future.
