  • Imej CorneyAndLind Develop a video conferencing platform & app $1300.00 AUD

    “This project was originally given a timeline for completion in 3 months. We waited 1 year, 2 months, before Sun X raised a dispute (on Freelancer) because he was unable to complete the project. We had issues with who we were dealing with, in that we awarded the project to a David Liu, then the project build was one Eric Li, then finally a dispute raised by Sun X. In fairness, there were difficulties with other technical support, but due to lack of communication; a lack of understanding of the scope we had agreed to; and a lack of technical knowledge - this project failed and we we were left with a half completed App to what was originally agreed to.”
