    “Extremely unprofessional and lacks any programming skills to complete project, even though he accepted and said will deliver in around 10 days. I've even set up a special server for him to work on and he has done not even 10% of the work. No communication at all, promises every time I ask that he will do it. After 30 days have passed he says "sorry sorry. Ill do it before sunday. Im signing big project and have no time. I`ll do it and give you for free (twitter)". Well, he doesn't even do that, doesn't give me what he worked on and stays silent when I asked for ending the project. I absolutely will never hire him again and will make sure that everyone on Freelancer knows that he's simply unable to fulfil projects and has not even the decency to respond to clients. I repeat, do not hire him - you will waste your time and money.”
