Who I am

I'm Areum Seo — a localization professional, project manager, linguist, and builder working across Korean, Japanese, and English. I came to Tokyo on a MEXT scholarship, completed a master's in applied linguistics at Tokyo University of Foreign Studies, and spent years teaching Japanese at Waseda and Korean at JCFL before moving into industry.

My professional work spans localization QA, translation, project management, and language operations — with past experience at Amazon Japan, where I received a Customer Obsession Award. My expertise runs across linguistics, gaming, technical docs, marketing, and entertainment.

Lately I've been building. Python, SQL, Streamlit, Snowflake, GitHub. I hold a SnowPro Associate certification and have been earning credentials in data engineering and generative AI in Coursera. I don't call myself a developer yet — but I ship things, and I keep going.
