The Online English Bureau

Proofing, Teaching


Reliable, Accurate and Consistent


Hi, my name is Diahnn Theophilus. In 2015, after 25 years in industry including 15 years in translation I decided to go freelance. I set up The Online English Bureau, through which I offer: Translation, Proofing, and Teaching.


Quality translation is very important to me. I achieve accuracy and consistency by applying glossaries, style guidelines and proofreading. I am a member of The Chartered Institute of Linguists and an Intermediate member of The Society for Editors and Proofreaders.


I have an excellent knowledge of translation tools, with 15+ years use of Trados and 5+ years use of Across. I use PerfectIt3 and Apsic Xbench to double check my text before hand-off. If you need some finishing touches and editing then I can apply styles, a table of contents etc., I’m happy to help as I have advanced knowledge of MS Word.


I specialise in translation for Business and IT (Marketing Materials & Websites, Tenders & Contracts, Technical Manuals). I have an MA in Applied Translation, a BA honours degree in Languages, Busin­­ess and IT, and a Professional Development Certificate in Management Studies.  I have worked for Xerox, Fusion Inc, Peopleclick, Hobart Welding, RayProof and IDC Loctite, I am therefore well versed in Business, IT and Engineering terminology.


I also work on Marine Biology/Zoology projects and translate restaurant menus. As a qualified Scuba diver, I support the Project AWARE campaign to protect our oceans.






Websites: Xerox product pages and knowledge bases. Landing page for a supplier of Medicinal and Aromatic Plants.

IT/Printing: User Interface (UI) messages for printers, print drivers, mobile phones. Technical manuals, User guides. Electronic Document Management Systems (EDM), FileNet and Enterprise Content Management (ECM), Interactive/e-learning.
