Provide data entry, cleaning, analysis, and spreadsheet automation services for small businesses, agencies, and individual clients on a freelance basis. Work spans the full data lifecycle — collecting and entering records from PDFs, forms, and web sources; cleaning and standardizing messy datasets; building formulas, macros, and dashboards to automate recurring reports; and structuring data systems for long-term reliability. Typical projects include migrating contact lists into CRM-ready formats, deduplicating and validating large spreadsheets, building automated Excel/Google Sheets dashboards with VBA and Apps Script, and turning raw datasets into clear summary reports with visualizations. Tools used regularly: Excel, Google Sheets, Power Query, SQL, and Python (pandas) for larger datasets. Focused on accuracy, fast turnaround, and clear communication — most projects are delivered within 1–5 days depending on scope, with a validation pass before delivery to catch errors before the client sees them.
