This person, not a professional, he just copy and paste stuff from the internet. He began by sending a demo "boost", saying it was his framework, after which he made some modifications to fit the needs of the project, and requested the release of money, released the money, now does not answer emails, skype is off-line all the time, answered a few messages saying that come into contact in skype, but never did. Since inability to finish the project, would be better to return the money, and canceled the project without resentment, but did not! The little code that he presented, does not work, does not have exceptions to handle errors, each error the application terminates with segmentation fault. DO NOT HIRE THIS PERSON FOR ANY SERVICE, YOU WILL ONLY LOSE TIME AND MONEY. I am reporting incomplete project, two months after the deadline, after waiting for his contact info, after sending sms to mobile, after fulfilling all the requirements expected, including payments.
