Back to original languageAbout Victor
- I am a professional focused on data automation and processing with Python and SQL.
I specialize in developing solutions that transform raw datasets into structured information ready for analysis, automating repetitive tasks and reducing manual work.
I mainly work on projects related to:
• data cleaning and transformation
• process automation with Python
• processing datasets in CSV, XML, and Parquet
• SQL queries and data analysis
• building small end-to-end data pipelines
I have developed my own data engineering projects using real datasets, including data ingestion, validation, transformation, storage in Parquet, loading into SQLite, and generation of analytical outputs.
My goal is to help companies and teams work with data more efficiently through simple, robust, and automated solutions.
