Unfortunately the freelancer didn't delivered results on time and outsourced to other person, which ended up delays in project delivery.

Slobodan was provided many complicated tasks but he performed them easily. I found him to be an effective communicator, and worked very well with him. He was studious, willing to learn new things needed for his job. He was open to proposed changes and feedback. He's a focused, detail minded person who does not need much direction. Slobodan has a strong work ethic, and his work is always completed with high quality while maintaining a high level of accuracy.
