Yuhan is building their profile!

I turn messy Excel/CSV files and PDF documents into clean, reliable, ready-to-use data. I help with data cleaning, deduplication, validation, PDF-to-Excel extraction, Python and VBA automation, web data extraction, and ERP/SAP/WMS logistics data preparation. Every delivery includes clear outputs, validation notes, and reusable instructions or code when applicable.
