Android App Game Developer

45 hrs @ $44.44/hr
Earned $1,744
“BEWARE! DO NOT HIRE. HE IS A KNOWN FRAUD along with his accomplice Jin @ https://www.odesk.com/users/~01a1fe7a5924946652The contractor did not make any of his commitments. He seriously misjudge the time he would take to work on this project. His misjudgment impacted everything else that I had going on around the development of the app including marketing deliverables, graphic logos, feature banners, etc. In addition, the contractor heavily lacks communication which also hindered me from doing what I needed to do to make a successful app. I have had to cancel multiple meetings with my marketing and graphic designing partners on several occasions due to his lack of communication and inability to deliver and make deadlines.Here are reasons to not trust or hire this contractor:1. He broke the contract.2. Every deadline we set, he missed or did not deliver on that due date.3. He showed extremely poor communication throughout this entire project.4. Misjudged project duration. The project was expected to be completed in 20 days and it was approaching 60 days before he realized he would not be finishing the project and I ended the contract.5. I payed him 87.5% of the total agreed upon cost of the project and the project was not even 20% completed.It was a very poor experience with a very poor contractor. I lost valuable time and money. Fortunately oDesk is taking the necessary measures to assist me in recovering my loses and I do appreciated their swift and concerned response to my experience.”
