I am a native English speaker and, as an accountant by qualification, I have a very good eye for detail, and am a stickler for getting things right! Having been involved in a number of database migrations before, I understand the scope for errors, things ending up in the wrong places, or even pieces of information going missing altogether!
Cross-checking the data between the two systems is no problem, and it would be a pleasure to have the opportunity of working with you on this project.
