Portfolio: language and content services by a writer, translator, and transcription specialist

Curious about the expertise behind my language and content services?

This page offers an overview of my work as an SEO copywriter, English ↔ Dutch translator, and transcription specialist. I have worked with language for over 15 years, and have been a full-time freelancer for the last 8. What you will find here is a carefully selected collection of clients and projects I am proud of. You can also find more details on my LinkedIn profile.

My work as a copywriter

Since 2016, I have been working with a regular group of clients, including marketing agencies such as SUM Digital and content agencies like Captain Words. I also regularly create content for websites, including de BouwApp, and have started learning how to implement content directly via CMS platforms such as WordPress.

I also write in English for various clients, including SitePodium and SUM Digital. My copywriting work is versatile, ranging from blogs and landing pages to customer stories and SEO-focused web copy.

Experience as a transcription specialist

Over the past few years, I have specialised in transcription—especially for medical research projects. Clients include QQFS, Amberscript, Qualmedic, Pharmore Research, and QualWorld.

I deliver complete transcripts of Dutch-language interviews and conversations, often translated into English or combined with content analysis. I have also completed transcription projects for research firms and translation partners such as Peak Translations.

Translation projects: English ↔ Dutch

Translation is the service I have been offering the longest. What began during my university years has become a central part of my business. Examples include:

  • University of Glasgow – academic texts during my time in Scotland
  • DailyArt app – cultural and educational content
  • SUM Digital, SitePodium, de BouwApp – ongoing translation assignments
  • Happy Neighbours (SitePodium) – book translation from Dutch to English
  • Studio LNRD – full website translation

Independent assignments and publications

In addition to long-term clients, I also work on a variety of one-off assignments. Some examples:

  • Blog articles for ProLinker / Freelancer.nl, such as Freelancing from abroad
  • Buying guide The best e-reader on Boeken-top-10.nl
  • Website translation for Studio LNRD
  • Client cases and blogs for SitePodium
  • Content for de BouwApp, including the profile of Diana de Klerk
