    For a task where many freelance developers had told us would take more than 2 to 3 months of work, Xayyavong delivered the requirement in ten days. Some parts of the task were outside of her technical zone of comfort, but she was open to receiving guidance and feedback and her communication was fast and timely. I needed to be able to showcase a proof of concept and Xayyavong was instrumental in delivering on time with the required quality. I enjoyed working with her and would recommend hiring her if you are able to keep communication lines open and provide guidance and problem solving as needed.
