    “Don't trust this guy. My project was for an Android and iOS native app. We agreed the price for the whole App project and he asked me to split the mobile app project in several parts (Design, API, Databse, Android App, iOS App etc.) which I agreed to do. So he did Design part and API part and I paid for it. Now we were supposed to start mobile application development and the freelancer asked me to increase my budget for the App project while we already agreed on a fixed price in advance. I told him that I refused to increase the budget since we already agreed on the price. Now the freelancer is not replying in Skype since 1 week while his status is "online" in Skype. This is absolutely unacceptable and unprofessional. Do not trust this person (beware, he is from China...). I lost $450 because of him because the design he produced was made half in one software and the other half in another software, this is quite messy and the API is not working properly and not finished, he told me that I should not worry and that he would finalize the API when we start the next step of the App development. So basically I would have to ask another freelancer to start API over and clean the design mess. I have worked on dozens of project on freelancer website and I would say that this is my worst experience and I would definitely not recommend services of this Freelancer. If you need more details you can contact me via Freelancer and I can provide all proofs and chat conversations history.”
