About Christina

I support companies and organizations in writing, revising, and structuring texts – clearly, carefully, and tailored to the target audience.

My focus is on copy editing and editorial work, as well as audio scriptwriting. As a podcast editor & voice artist for thoughtful storytelling and precise texts, I make content audible – and effective. From idea to speakable text: Documentaries, e-learning, image films, advertising, cultural features, podcasts, audio guides, radio moderations.

Additionally, I have experience in the clear presentation of complex content – including in the education sector and in conveying digital topics.

Services:
– Copy editing & Proofreading
– Topic development & Concept
– Text creation & Editing (also for audio content)

– Revision and structuring of documents (incl. PDF)

Reliable implementation, clear communication, and on-time delivery are a matter of course for me.

Work samples can be found in my portfolio. I am happy to send further work upon request.
