translation, editing, proofreading

Let me introduce myself

I am a translator and editor working with English and Polish. Active professionally since 2010, I have handled an array of diverse tasks, ranging from individual texts through book-length translations and complex high-volume projects. Working both freelance and in large publishing houses has helped me grow into a well-organised and driven person that I am today, with the added perk of gaining an in-depth knowledge of the publication process.

For the past few years I have been focused on medical editing, which made me appreciate the simple yet precise style of scientific writing. Having some experience with HTML, CSS and programming languages, I am confident working with more technical documents and have no trouble learning new software. Occasionally, though, I still very much enjoy challenges that allow a greater degree of creative liberty, such as a literary work or marketing copy.

What I can help you with

Translating in the English-Polish and Polish-English combinations. My past projects include academic papers, marketing texts, websites and basic legal documents. I was also fortunate to join a large team to collaborate on a major MMORPG localisation.
My published translations include a couple of brilliant books on architecture and two of Roald Dahl’s classics. Having the privilege of translating good authors is a humbling experience.
Editing texts in English, written by native and non-native speakers. My area of expertise is medicine and health sciences.
Editing involves checking the text for style, clarity and accuracy to make sure it is consistent, coherent and appropriate for the intended audience. Grammar mistakes, punctuation and typos are fixed.
Proofreading is one the final stages of preparing a text for publication. It may involve checking a typeset text for errors before printing or clicking through a website before it is launched.
Proofreading should be focused on fixing typos, spelling mistakes and formatting issues. It should not involve major stylistic reworkings.
Transcripts of audio-visual content can be a verbatim record of every utterance, including fillers such as “umm” or stuttering, or they can be cleaned up for clarity and ease of reading.
I am experienced in transcribing highly specialist medical videos, where great accuracy and attention to detail are required already at the stage of producing verbatim texts.

On the importance of commas

A panda walks into a café. He orders a sandwich, eats it, then draws a gun and fires two shots in the air.

“Why?” asks the confused waiter, as the panda makes towards the exit. The panda produces a badly punctuated wildlife manual and tosses it over his shoulder.

“I'm a panda,” he says at the door. “Look it up.”

The waiter turns to the relevant entry in the manual and, sure enough, finds an explanation.

“Panda. Large black-and-white bear-like mammal, native to China. Eats, shoots, & leaves.”
