Email a briefAbout me
I'm Jisung Yoon, a native Korean speaker based in Gwangju, South Korea. I studied English Language & Literature at Chosun University, and I run Yunju Company (윤주컴퍼니), a small registered sole proprietorship, under my own name.
I'm new to working with overseas clients, so instead of a client list this page shows spec samples: pieces I wrote to show how I work. They are not paid client work, and the brands, people and data in them are fictional. Each one is labeled.
How I like to work: you send a written brief and your files, I ask any questions before I start, and I send back finished files with a short note on anything I changed or need you to confirm. No calls or video meetings — I'll answer everything in writing.

Writing & translation portfolio
Seven pieces in one file: SEO product description, blog excerpt, landing page, 3-email cold sequence, EN→KO marketing copy side by side, a singable Korean lyric adaptation, and a spreadsheet cleanup. All brands and data fictional.
Open →Korea market snapshot: US skincare brand
Format of the $150 snapshot for a hypothetical brand ('Brand X'): channels (Olive Young, Coupang, Naver, Kakao), live price benchmarks read from public pages on 2026-10-30, regulation notes, and a source list. Facts, estimates and assumptions are tagged separately.
Open →3-email welcome sequence
Welcome, story and offer emails with subject lines, preview text and CTAs for a fictional quiz brand, 'InnerMap'.
Open →Spreadsheet cleanup: before → after
A messy order export turned into one clean table with formulas, a summary sheet that updates when rows are added, and a change log. Fictional data.
Open →10 social captions (EN + KO)
Instagram, X and LinkedIn captions for a fictional coffee brand, each with a natural Korean version.
Open →SEO blog post, ~1,270 words
Keyword-targeted how-to article with meta title/description and H2/H3 plan, plus Korean keyword and meta.
Open →EN → KO product page localization, before/after
English product page, a literal 'translationese' Korean version, the localized Korean page, and an 11-row table explaining each change.
Open →Landing page copy (EN + KO)
Subscription landing page: hero, benefits, how it works, FAQ and CTA, in English and localized Korean.
Open →Services & prices (USD)
Fixed price confirmed in writing before I start. Bigger or rush files get a quote first.
