  • image de jackp10 fullstack developer needed to help the completion of a website £50.00 GBP

    “Working with Li it has been a real nightmare. First of all, he is a HE and not a SHE. He has a picture of his girlfriend as main profile, which is already misleading. I hired him to help me complete my project. Not only he was very unprepared with what it should be a standard developer knowledge (he did not know how to set up apache, nor mysql or virtual hosts), but then, after 2 days, he realised he could not deliver and he step back from it. The problem was that I created a milestone that I had to release in order for him to start working and, after he decided to leave the project, he refused to give back the money. Not only that, but he threaten me to not give me the money unless I was leaving him 5 stars review, which is unacceptable. Be very careful when you deal with this person. It is not professional, nor prepared or knowledgable. On top of that, his level of English is not near good enough to make a decent communication, which is vital for explaining the job. Very awful experience!”
