What I'm looking for

I'm looking for remote work where I can improve multilingual AI data through Japanese review, transcription, and annotation, while also applying my GA4 and marketing-analysis experience.

I review and correct AI-generated Japanese across RWS, Outlier, Appen, iMerit, OneForma, SIGMA AI, and Datoviaplayhouse, improving naturalness and linguistic accuracy for LLM training data.

I also transcribe spoken audio in Japanese, Korean, and English and perform annotation and labeling work to support machine-learning datasets. I work independently across multiple freelance platforms.

Previously, at G-One Corporation and Medical Information Network Co., Ltd., I built the department's first data-analysis workflow, including Excel templates and GA4 configuration. I analyzed conference registration, attendance, and website performance data for pharmaceutical-company clients.

At Colantotte, I built budget and ordering workflows, analyzed EC and sales data using GA4, created standardized templates, and trained temporary staff. My background combines Japanese, Korean, and English language work with practical marketing analytics.
