    “Initially knowledgeable - likely very much so. Unfortunately communication is very minimal once you agree... and the project was delayed by a week... and handed off to someone else without my permission (Due to a death in the family, which I understand) - but they still wanted yet another week (the 'new team'). That makes the project at least 2 weeks past the original agreement, when it was made clear at the start this was an urgent project. I would love to recommend Qiang, but unfortunately cannot at this time. Others have all had awesome experiences, so I assume this is not a normal occurrence, but have to post honestly. Give her a chance, but be prepared for probable delays in replying. Most times it took 24 hours or more and after multiple nudging even though I can see she had seen the posts within 2-3 hours. Rating explanations: Quality - unknown, no code provided so I have no idea. Communication - not good, drops off. Expertise - I agree she likely has it, others have been thrilled. Professionalism - polite Hire again - unfortunately this is a no for me. I wish Freelancer would allow 0 responses because it may be unfair for me to star like this. Hopefully others have awesome experiences, obviously my timing wasn't great with her workload or life.”
