About this Gig
Are raw, messy, or unstructured datasets holding back your AI models and database performance?
High-quality data is essential for accurate AI model training, machine learning pipelines, and optimized SQL performance. I will help you clean, format, transform, and structure your data using Python (Pandas/NumPy) so it is 100% production-ready.
What I can do for your data:
Data Cleaning: Handle missing values, remove duplicates, and fix formatting issues.
AI & ML Prep: Tokenization prep, normalization, and text preprocessing for LLMs or models.
SQL Structuring: Convert messy CSV/JSON files into clean relational schemas for databases.
Why work with me?

I accept CSV, Excel (.xlsx), JSON, SQLite, or raw text files. I will process them and deliver clean, production-ready files along with the Python source code.
Can you prepare datasets for AI models or LLMs?
Yes! I specialize in data formatting, normalization, handling missing values, and tokenization preparation specifically structured for machine learning pipelines and AI training.
Do you provide the Python source code?
Yes, absolutely. You will receive the fully documented Python scripts (using Pandas/NumPy) so you can run and reproduce the data cleaning process anytime.
