    Sergei seemed to have most of the skills necessary to complete the assignment but also seemed to be learning on the job (such as the differences between XSLT engines). He was very personable but was not good at setting and meeting deadlines. His QA/Testing of the work delivered needed significant improvement. Sergei also needed to communicate better to let the us know when he has run in to difficulties so we can adjust the schedules for other projects and if necessary find some assistance for him.

    Sergei is an exceptional worker. He has great skills and a great thought process. His availability was limited at times, but beyond that I have no issues with anything he ever has done for me. He is a self starter and makes project recommendations frequently.
