I provide practical data services for small businesses and teams that need clean, structured data. I help with Excel/CSV data cleaning, ETL automation, web data collection, and machine learning prediction models. I can clean messy files, remove duplicates, handle missing values, merge datasets, automate repetitive workflows, and prepare data for reporting or analysis.
