Project details
Is messy, duplicated, or unstructured data holding back your analytics and business performance? I will clean, transform, and structure your raw data into production-ready datasets.
As a Data Specialist (B.S. in Science & Technology from UNIFESP), I specialize in building reliable data pipelines using SQL, Python (Pandas/NumPy), and Power Query to turn broken spreadsheets into clean, relational models.
What I offer in this project:
• Data cleaning, deduplication, and missing value handling
• Complex SQL queries, view creation, and table joins
• Advanced Power Query transformations & M code optimizations
• Star-Schema and Snowflake relational data modeling
• Reusable Python scripts for automated ETL processing
Why choose me?
• Data Accuracy: Rigorous validation to ensure 100% metric consistency.
• Scalable Architecture: Models built to handle growing data seamlessly.
• Clear Communication: Daily updates and structured technical handover.
Stop wasting time fixing broken data manually. Select a tier to clean your datasets!
