    Enthusiast PHP developer needed for complex projects
    This contractor cheated us by using someone else to work for him. His punctuality is good, he worked exactly 7h/day, but not the quality we observed via the interview. Be careful.
    Freelancer's Response
    Since they provide very unclear requirements, for example, they just said they need a message system like oDesk and that's all, and it's a legacy project and there is no documentation for exiting code/existing database structure at all, I had to guess almost every fields in db and did lots of investigation, so that cost most of my time and that made them felt my performance was poor.. It's really funny. I also confused why I could not ask help from my friends with some tricky issues came up, the goal was to complete the project asap and I did not share any private information about the project, just pure technical communication so what was the problem? I tried to be nice so when they asked for unreasonable refund I accepted but they kept doing so based on their unprofessional judgment. The owner of the project lack of basic IT knowledge and their project manager lack of basic management experience either, that won't make the project success for sure.
