  • imagem de Amjad N. Project for Arginaldo Cesar B. $500.00 USD

    “Mr. Cesar is skilled resource but his ability of delivering projects on time is always issue. I tried him on few projects but all the time he took too many extra days to complete the project. The most thing I did not like, his attitude and pushing on release of payments. As soon he think he finished a milestone, he will start pushing for payments. He would not listen to you but may threat stopping work. I assigned him to critical task with certain due date. He did not complete his work on time on agreed date. He finished partial work but started asking to release payments much more than the amount of work he completed. He is not trust able at all on dispute situation. We ended up in dispute due to not agreeing on completed work and release of payments. He had access to my Virtual Machines with domain accounts which he created during the configuration process. I did not know those accounts and I did not change the passwords for those accounts. He logged into my environment and messed up all of the completed work which was 100% paid to him. Now I already paid him more than $500 but I did not get anything as all of my works is damaged due to his criminal approach.”
