R programmer required for small statistics project

“Overall a very good experience with no problems of any kind. The contractor communicated well beforehand and during the process, which is important for complex requirements. The output - her R code - was solid and did what it was supposed to do. She was scrupulously honest about billing, returning a few dollars that was mistakenly charged due to inexperience with oDesk systems before we even noticed it. We have been slow to give feedback due to volatility in our team caused by the turmoil in the financial markets, but this should not be taken in any way negatively - we would definitely use her again.”
