  • käyttäjän truelifeajf kuva Urgent - need wordpress dev now to finish off plugin $312.37 AUD

    “A frustrating experience. Like most coders from non-English speaking countries / cultures, he had REALLY bad communication. I use a custom-coded job management system so communication is easy, and clear. He agreed that he would comment when he started a task and set the status to "in progress". Not ONCE did he do this. After a week of him not communicating, I assigned a task marked as urgent and he decides to ignore it because he hasn't started on it yet. In the mean time he spends the entire day working on other tasks that aren't urgent. So not only did he decide that ignoring that request would be a good thing, but that he should focus on non-urgent tasks instead. He insisted that he didn't need to comment on the task that was urgent because he hadn't completed it yet... completely ignoring that he had agreed not to do that. When I reminded him of this... no acceptance of fault, no apology, just an insistence that he's "working hard". This is just ONE example of poor communication. If you can't follow the basic rules and then you don't take responsibility when you ignore the rules... you're not a good coder.”

    “I tried many developers, and this one the best. You can see I have over 400 employer reviews, so I do hire a lot of people so saying that he is the best means A LOT. He simply is the best.”
