About

Language meets
business reality

I'm a native Norwegian translator and localisation specialist, and something of a globetrotter. Currently based between Norway and El Salvador, I've lived and worked across England, the USA, Mexico, Colombia, Puerto Rico, Latvia, and Panama. That breadth of experience isn't just a fun fact, it shapes how I approach every single project.

What sets me apart is a genuine business background. I've founded and run companies across multiple continents, which means I don't just translate words. I understand the context, the industry, and the people behind them. Whether it's an e-commerce store, a legal document, or an ad campaign, I know what it takes for language to actually land.

For assignments where tone, accuracy, and cultural fit are critical, where the target audience is very specific and getting it wrong isn't an option, I go deep. That means thorough research, careful terminology work, and a focus on how the content feels to the end reader, not just whether it's technically correct.
