About John

Your Swedish
language partner.

Independent expertise.
Direct collaboration.

When you work with JW Translations, you work directly with me—from the first brief to the final review.

I’m a native Swedish translator based in Malmö. Since founding JW Translations in 2010, I’ve supported global brands through recurring translation, localization and review assignments—from product interfaces and medical documentation to industrial content and travel campaigns.

My academic background brings together translation, English, Japanese and psychology. It informs a careful approach to meaning, tone and the reader’s perspective, whether I’m refining a Swedish interface or reviewing a machine translation.
