Across projects with Twigfarm, Muhayu, Future Nuri, and BQ AI, I review Korean and Japanese OCR data, curate Korean grammar datasets, correct speech-to-text transcripts, and monitor news content. My work includes bounding-box and text-segmentation review, transcript correction, and metadata checks.

For IT Korea, Daeguk G&S, Hanguk IT, AT&I, and AGIT, I transcribed and reviewed historical Korean public records, land registries, and mixed-script materials. I checked difficult archival layouts and flagged unreadable text.

At Korea Institute of Public Finance (KIPF), BJ Public, Buka, and Hanbit Academy, I edited and proofread technical books, financial reports, and policy publications. I also checked factual consistency, style, formulas, tables, and diagrams.

I have a B.A. in Library and Information Science with a minor in Japanese Language & Literature, and I hold KBS Korean Language Proficiency Test Level 1 and Hanja Proficiency Certification Level 2. My work also draws on MARC cataloging, metadata review, and document digitization.
